The number resellers get wrong

A £25 sale feels like £25. It is not. On an item that cost you £8, with a fee and postage, your real profit is what is left after all of it. Track that per item and you quickly learn what is worth sourcing again, and what to stop buying.

Fee models differ: on Vinted, sellers usually list free and buyers pay a protection fee; eBay removed most private-seller fees; business sellers pay. Set the fee that applies to you. More in Vinted fees and eBay fees.
