Selling online is one of the most accessible ways to earn extra money — and in 2026 there are more platforms and buyers than ever. Whether you're clearing your home, buying items to resell or creating products, this guide covers everything you need to do it safely and profitably.

Key principle

The most successful online sellers treat it like a business. They track costs and profits, take quality photos, write detailed descriptions and provide excellent customer service.

1. Best platforms to sell on in 2026

Platform	Best for	Fees
eBay	Almost anything, electronics, collectibles	~12.9% final value fee
Vinted	Second-hand clothing	0% for sellers
Facebook Marketplace	Local sales, furniture	0% local, 5% shipping
Etsy	Handmade, vintage, digital	6.5% + listing fee
Depop	Vintage clothing, streetwear	10%

2. What sells best online

Clothing and fashion — biggest category. Brand names and vintage pieces sell fastest.
Electronics and tech — high demand, high prices. Always test before listing.
Collectibles and vintage — eBay is king. Old toys, vinyl records, vintage watches.
Books and media — lower individual prices but easy to source and list in bulk.
Sports equipment — used gym equipment and bikes always in demand.

3. How to stay safe from scams

Common scams to avoid

Overpayment scam — buyer sends more than asking price, asks for difference back. Never refund before payment clears.
Fake PayPal emails — always check payments directly in your PayPal account.
Local pickup safety — meet in public places for cash transactions. Never invite strangers home.
"Item not received" fraud — always use tracked postage. Without tracking you have no protection.

4. How to photograph and describe your items

Natural light — take photos near a window. Avoid flash.
Multiple angles — front, back, sides, labels and any flaws. Hidden flaws lead to returns.
Keywords in the title — include brand, size, colour and features. "Nike Air Max 90 White Size 10" beats "Trainers".

5. How to price for maximum profit

Search for your item on the platform, filter by "sold listings" and see what similar items actually sold for. Price yours at or just below the average sold price, then factor in all fees and shipping to ensure you're making a profit.

6. Realistic earnings

Approach	Time/week	Monthly earnings
Clearing out your home	2-5 hrs	£50 - £300 (one-off)
Reselling (charity shops)	5-10 hrs	£200 - £800
Part-time reseller	15-25 hrs	£500 - £2,000
