How to research comps, account for platform fees, and avoid the pricing mistakes that cost new sellers money.
Pricing is the first thing buyers judge, and it’s easy to get wrong in either direction — price too high and your listings sit unsold; price too low and you’re funding someone else’s profit margin.
Search sold listings, not active ones. An active listing at $80 tells you what the seller wants; a sold listing at $52 tells you what a buyer actually paid. Most platforms let you filter search results to sold/completed items — use that filter every time you price something new. Pull at least five comparable sold listings before you set a price, and weight recent sales more heavily than ones from months ago, since collectibles and resale markets move.
Condition matters more than category. A near-mint item and a well-loved one in the same category can differ by 30-50% in realized price. Don’t average across conditions — find comps that actually match the condition of what you’re selling.
Every platform takes a cut, and it’s easy to price an item, sell it, and then be surprised at what actually lands in your account. Whatnot and similar live-commerce platforms typically charge a percentage of the final sale price plus payment processing; fixed-listing platforms like eBay charge a final value fee plus payment processing; some platforms add listing fees regardless of whether the item sells.
Work backward: decide what you actually need to net from a sale, then add back the platform’s total take (commission + payment processing, both as percentages) to find your listing price. A simple way to do this: if a platform’s total fee load is 13%, divide your target net by 0.87 rather than just adding 13% to your target — the math is different because fees come off the sale price, not your net.
New sellers often assume the way to get noticed is to undercut everyone. In practice, buyers on collectible and resale platforms are shopping for trust as much as price — a seller with reviews, clear photos, and accurate descriptions can price at or above the median and still sell, while a rock-bottom price with no seller history can actually make buyers suspicious. Price competitively within the range your comps establish, not below it.
Your first few sales are data. If something sells within hours, you probably priced it low. If it sits for weeks with views but no sales, the price (or the photos, or the description) needs a second look. Treat your early listings as calibration, not a one-time decision.
