Charity Shop Reselling: How to Turn Thrifting into Side Income

SYM

Charity shop reselling — buying undervalued items in charity shops and selling them online for a profit — has grown from a niche hobby into a legitimate side income for thousands of people across the UK. With platforms like eBay, Vinted, and Depop making it easier than ever to reach buyers, and charity shops offering an endless stream of underpriced stock, the opportunity is genuine. Some resellers earn a few hundred pounds a month as a casual side hustle; others have built full-time businesses. Whether you want to earn extra cash to boost your savings or build a scalable income stream, this guide covers everything you need to get started. Track your reselling profits alongside your other financial goals with the SYM app.

How Charity Shop Reselling Works

The concept is simple: you buy items from charity shops at their low retail prices, then resell them online to people specifically searching for those items at a higher (but still fair) market price. The profit margin comes from the gap between the charity shop price and the item's true market value. Charity shops price items generically — a wool jumper might be £4.99 regardless of whether it's from Primark or Burberry. A book might be £2 whether it's a common paperback or a sought-after first edition. As a reseller, your skill is spotting the items whose market value significantly exceeds their charity shop price tag. The key to success is knowledge: understanding brands, materials, trends, and what buyers are searching for on each platform.
  • •Buy items at charity shop prices (typically £1-10) that have a higher resale value online
  • •Clean, photograph, and list items on platforms like eBay, Vinted, or Depop
  • •Ship items to buyers using Royal Mail, Evri, or platform-provided shipping labels
  • •Profit = selling price minus purchase cost, platform fees, and shipping costs
  • •No special qualifications needed — just an eye for value and willingness to learn
  • •Start small with items you already know about (e.g., your area of interest or expertise)

What Sells Best: Items to Look For

Successful reselling starts with knowing what to buy. Not everything in a charity shop is worth reselling — the skill is identifying items with a significant gap between their charity shop price and their online market value. Over time, you'll develop an instinct for which items are worth picking up, but here are the categories that consistently perform well for UK resellers. The golden rule is to check the sold listings on eBay before buying anything — this tells you what the item actually sells for, not just what optimistic sellers are asking.
  • •Branded clothing: Premium and designer labels like Barbour, Joules, White Stuff, Boden, North Face, and high-end brands like Burberry, Ralph Lauren, and Ted Baker consistently sell well
  • •Vintage clothing: Genuine vintage pieces (pre-2000) from brands like Levi's, Adidas, Nike, and band t-shirts command premium prices
  • •Books: First editions, signed copies, academic textbooks, and out-of-print titles can sell for 10-100x their charity shop price. Use the eBay app to scan barcodes quickly
  • •Vinyl records: Check for original pressings of popular albums. Condition is everything — look for records that have been well-stored
  • •Board games and puzzles: Complete, vintage, or out-of-production games sell well, especially at Christmas
  • •Pyrex, Le Creuset, and quality kitchenware: Cast iron and vintage Pyrex patterns have dedicated collector markets
  • •Jewellery: Hallmarked silver, quality costume jewellery, and branded pieces (Monet, Trifari) are often underpriced

Which Platforms to Sell On

Choosing the right platform for each item significantly affects your success rate and profit margins. Each major UK reselling platform has its own audience, fee structure, and sweet spot for different types of items. Using multiple platforms simultaneously maximises your reach, though it also increases the admin work. Many successful resellers start on one platform and expand as they get more comfortable with the process.
  • •eBay: The most versatile platform with the largest audience. Best for collectibles, electronics, branded items, and anything niche. Seller fees are approximately 12-13% of the total transaction. Auction format works well for rare or highly sought-after items
  • •Vinted: Zero seller fees make it excellent for clothing. Very popular in the UK for everyday fashion brands and mid-range labels. Best for women's, men's, and children's clothing
  • •Depop: Skews younger (Gen Z and Millennial audience). Best for vintage, streetwear, and trendy fashion. Charges a 10% fee on sales
  • •Facebook Marketplace: Good for furniture, homeware, and bulky items where local collection avoids shipping costs. No selling fees for local pickup
  • •Etsy: Best for vintage items (must be 20+ years old) and craft supplies. Fees are approximately 9-11%
  • •Amazon: Selling used books via Amazon can be highly profitable — their FBA (Fulfilled by Amazon) service handles storage and shipping

Pricing, Fees, and Calculating Profit

Understanding the true cost of reselling is critical to ensuring it's actually profitable. Many new resellers focus on the selling price without properly accounting for fees, shipping, packaging, and the time invested. A thorough profit calculation considers every cost involved in getting the item from the charity shop shelf to the buyer's door. Using a simple spreadsheet or the notes feature in the SYM app to track purchases and sales helps you identify which types of items are genuinely profitable and which aren't worth your time.
  • •Always check eBay 'sold' listings (not just active listings) to see what items actually sell for
  • •Factor in platform fees: eBay ~13%, Depop 10%, Vinted 0%, Facebook Marketplace 0%
  • •Include shipping costs: Royal Mail 2nd class large letter from £1.85, small parcel from £3.35
  • •Budget for packaging: padded envelopes, boxes, tissue paper, and tape typically cost 30-70p per item
  • •A simple profit formula: Selling price – (purchase price + platform fees + shipping + packaging) = profit
  • •Aim for items where you can at least triple your purchase price after all costs
  • •Track all purchases and sales for tax purposes — you'll need these records if your turnover exceeds £1,000

Tax Rules for UK Resellers

Understanding the tax implications of reselling is essential. HMRC has been increasingly focused on online sellers, and the rules are clearer than many people realise. Since January 2024, online selling platforms are required to report seller information and earnings to HMRC, so the tax authority has visibility of your sales. The good news is that most casual resellers fall well within the tax-free thresholds, but if you're building a serious side income, you need to understand your obligations.
  • •The Trading Allowance gives everyone a £1,000 tax-free allowance for trading income per year — if your total reselling income is under £1,000, you don't need to report it
  • •If your reselling income exceeds £1,000, you must register for Self Assessment with HMRC
  • •You can deduct allowable expenses (purchase costs, fees, shipping, packaging, mileage to charity shops) from your taxable profit
  • •Keep detailed records of all purchases, sales, fees, and expenses from day one
  • •VAT registration is only required if your turnover exceeds £90,000 (unlikely for most side hustlers)
  • •Selling personal possessions that have decreased in value is not taxable — the rules apply specifically to buying with the intention to resell at a profit
  • •Consider using accounting software or a simple spreadsheet to track everything

FAQ

Frequently asked questions about charity shop reselling in the UK.
How much can I realistically earn from charity shop reselling?+

Casual resellers spending a few hours per week typically earn £100-400 per month. More dedicated resellers who treat it as a serious side hustle can earn £500-1,500 per month. Full-time resellers with established operations and deep product knowledge can earn significantly more, but this requires substantial time investment in sourcing, listing, and shipping.

Is it ethical to buy from charity shops and resell?+

This is a common debate. The charity benefits from your purchase regardless of your intention — they receive the money and clear stock to make room for more donations. You're also providing a service by connecting items with people who specifically want them. However, it's worth being mindful of not clearing out all the bargains in shops that serve low-income communities. Many resellers focus on niche or collectible items that typical charity shop customers wouldn't buy anyway.

What tools do I need to get started?+

At minimum, you need a smartphone with the eBay app (for checking sold prices while in-store), a way to take decent photos (your phone camera is fine), packaging materials, and access to a post office or parcel drop-off point. As you scale up, a small ring light for photography, a kitchen scale for weighing parcels, and a label printer will save time.

How do I know if an item is worth reselling?+

Check eBay's 'sold' listings by searching for the item and filtering by 'Sold Items'. This shows you what people have actually paid recently. If the sold price minus your costs (purchase + fees + shipping + packaging) leaves a worthwhile profit, it's worth buying. As a rule of thumb, look for items where you can sell for at least 3-4x your purchase price.
