Know the minimum offer worth accepting before the offers arrive — and set auto-accept/auto-decline so eBay negotiates for you.

Minimum offer worth accepting

$22.97

keeps your 15% margin after fees — that’s 23% off your list price

Set auto-accept at: $22.97 or higher — never think about good offers again.

Set auto-decline below: $21.36 — lowballs disappear silently.

Absolute break-even (0% margin): $18.98 — accepting anything below this loses money. This is the same floor a repricer should never cross.

Your negotiation floor is the same as your repricing floor

Sellers who lose money on Best Offer almost never lose it on one bad deal — they lose it by accepting “just slightly low” offers repeatedly because the number felt fine in the moment. The defense is computing your minimum once, when you're calm, and letting automation enforce it.

That's the same principle behind floor-first repricing: Undercut beats the lowest competitor automatically but never crosses the per-item floor you set. Work the full math in the fee calculator, or read the price-floor guide.

FAQ

What is the minimum offer I should accept on eBay?

The price where the offer still covers item cost + your shipping cost + eBay fees + your minimum margin. Formula: (cost + shipping + per-order fee) ÷ (1 − fee rate − margin rate). Below that number you are paying the buyer to take your item.

Should I use auto-accept and auto-decline?

Yes — they turn Best Offer from a chore into a system. Set auto-accept at your minimum acceptable offer and auto-decline slightly below it. You stop negotiating every lowball manually, and serious buyers get instant gratification, which converts better.

Is Best Offer better than just lowering my price?

They solve different problems. Best Offer captures price-sensitive buyers without showing everyone a lower price. Lowering the list price (or repricing) improves search competitiveness for every buyer. Competitive commodity listings usually benefit more from repricing; unique items benefit more from Best Offer.

How does Best Offer interact with automated repricing?

They stack: the repricer keeps your list price winning against competitors (never below your floor), while Best Offer thresholds catch buyers who want to feel like they got a deal. Use the same floor for both — your minimum is your minimum.
