The deal
Pricing
Bidders
Free. Browsing, watching, and bidding cost nothing. When you win, you pay the hammer price plus the buyer premium shown on every sale before you bid — typically 15%.
Sellers
Nothing up front. Listing an estate sale is free. BidNasty earns the buyer premium when lots sell; you receive the full hammer price, paid out through Stripe after the buyer completes payment.
Power-ups
Optional and cosmetic-adjacent: strategic boosts bought with coins earned by bidding. You never need them to win — they are for playing the game harder.
