Best Offer Without Giving Away the Store
Bottom Line: Best Offer is a second door into the store, and the auto-decline is the bouncer — it never lets an offer drag a card under its floor.
Best Offer is on across my store. So is the guardrail. Those two facts together are the whole lesson: any buyer can offer on any card I list — and any offer that drags a card under its floor dies automatically, at 3 a.m., without waking me up or talking me into anything. Best Offer done right is a discount channel with a bouncer. Done wrong, it's a slow leak in every price you own. Here's my exact setup and the math under it.
The setup, in order
- Turn Best Offer on. Some buyers will never pay sticker on principle, and some of them are perfectly good customers at 10% off. Best Offer is how those sales exist. Off is a defensible choice; mine is on, because of step two.
- Set the auto-decline at 80% of list. Storewide rule: any offer more than 20% off declines itself, instantly, no notification drama. This is the line that makes step one safe. The buyer learns my boundary from the system — not from me, not in a message thread at midnight — and serious buyers come back with serious numbers.
- Hand-set the wall's floor: $2.31. The $2.96 cluster gets its own hand-set auto-decline at $2.31, because down at the floor the percentages and the floor math collide, and the floor math wins. Here's why that number: it costs me about $1.10 to mail a card before eBay's fees take their cut (the full build is How to Ship a Trading Card). Under $2.31, what's left after the mail and the fees doesn't cover the card — the "sale" pays me in negative. So $2.31 isn't a negotiating position. It's arithmetic with a gate on it.
Above the line: accept, counter, or wait
Offers that clear the auto-decline reach me, and they get judged on the card, not on hope:
- Accept when the number is fair against the card's comps and the card has been sitting. A good offer on a slow card is the market talking; listen. (The comp method is Pricing With Comps.)
- Counter when they're close — with the lowest number you'd genuinely be happy to pack the card for, stated once, plainly. A counter is a price, not an opening bid in an auction about your feelings. If they walk, the card goes back to waiting for its buyer, which it was already doing.
- Decline and wait when the offer is legal but wrong — above the auto-decline, below what the card is worth against solds. The system handles the insulting offers; my job is only the reasonable ones that are still wrong for this card.
The offers you'll actually see
Once the gate is set, the offers sort themselves into shapes you'll learn on sight. The lowball — half price, sent in the first hour — never reaches you; the system eats it, which is the system working. The fair-but-early offer lands on a card you listed yesterday at a number you'd take in a month; that's a patience test, and patience usually wins — a fresh card at a fair price hasn't met its buyers yet. And the multi-card offer, where a buyer names one number for several listings: judge the total, not your per-card pride. If the bundle total clears every card's floor with room, it's a good sale wearing a trench coat. The gate handles the dollars; these shapes are where your judgment lives.
The rule that protects all of it
Never negotiate under your floor in messages. The moment a buyer learns that the auto-decline is theater — that a sad story in the inbox unlocks a lower price than the system allows — every floor you own becomes a suggestion, and word travels. If you would truly take less for a card, change the floor itself, in daylight, with the floor math in front of you (that's The $2.96 Floor). A floor you revise on paper is a decision. A floor you break in chat is a leak.
Review the gate when the math moves
One last discipline: the gate is arithmetic, and arithmetic has inputs. Postage goes up. Fees change. The build gets cheaper or dearer as supply prices move. When an input moves, the floor math gets redone — in daylight, on paper, the way it was built — and the auto-decline moves with it. What the gate never does is drift: a number set from last year's postage is quietly wrong in this year's, and the system will enforce your stale math with total confidence. Floors are set from the world as it is. Recheck the world on the same schedule you recheck the prices — the weekly rhythm the store already runs on — and the gate stays the honest bouncer you hired.
The part people get wrong: building a floor with a gate and then climbing over it themselves. The auto-decline isn't there to be rude to buyers — it's there to be immune to your own 2 a.m. generosity. Let the system be the bad guy. It's better at it, and it never gets tired, lonely, or talked into anything.
Set the gate once and Best Offer turns from a leak into what it should be: a second door into the store, with the prices still yours on the other side of it. The companion lever — discounts buyers earn by bundling — is Quantity Discounts and Watcher Offers.
