What does this marketplace sale actually leave?
Three explicitly limited US seller-fee profiles from official schedules checked November 8, 2026. One item, one domestic order—not every category or account.
The bargain has a maximum buy price
Work backward from a sale scenario, actual fee amount and chosen profit target. A negative ceiling is a reason to stop, not negotiate harder.
Leave offer room without inventing a higher value
Turn your minimum acceptable item price into a listing-price constraint, then compare it with your own upper comparable price.
The sale made money. Did the whole trip?
Count driving costs and all active work, not just the minutes at the checkout. Use your actual vehicle-cost assumption, never a tax mileage rate.
Read for the decision, not the shopping rush
Six manuals worth opening before the box.
