Lot economics
Monthly volume (for plan choice)
Strategy: skip this lot
$22.60max bid
Current bid is already at or above your max. Do not chase — wait for the next lot.
- Net after sale fees & outbound ship: $57.60
- BuzzerBidder Standard tip at this max (2%): $0.45 — keep that in mind vs target profit
Standard vs Pro (at your volume)
Estimated Standard fees: $9.60/mo vs Pro at $10/mo (0% success fee).
Standard is usually cheaper until ~8.3 wins/mo at this hammer size.
How the strategy works
- Price the exit with realistic sold comps (not listing asks).
- Subtract marketplace fees, outbound shipping, inbound ShopGoodwill shipping, and profit.
- Compare that ceiling to the current bid — skip if you are already out.
- If the lot still makes sense, snipe near close instead of advertising an early high max.
- Use monthly wins × average hammer to pick Standard vs Pro on pricing.

Frequently asked questions
What is a ShopGoodwill bid strategy calculator?+
It turns eBay sold comps, fees, shipping, and the current bid into a max bid plus a simple snipe / skip recommendation — and compares Standard vs Pro fees at your monthly win volume.
How is this different from the max bid calculator?+
The max bid tool focuses on the dollar ceiling. This bid strategy calculator also factors current bid (chase risk), a snipe-vs-skip verdict, and whether Standard or Pro is cheaper for your volume.
Should I bid early or snipe?+
If comps support your max and the current bid is still under it, sniping near close usually keeps your ceiling quieter than early bidding. If the current bid already exceeds your max, skip — do not escalate.
Does BuzzerBidder guarantee a win at this max?+
No. A snipe only submits your max near the end. A higher proxy max, site issues, or network failures can still miss. Use the calculator as a money decision, not a win promise.
