Guide
Used inventory breaks the simple repricing playbook. The same model in "like new" and "acceptable" condition are two different products with two different buyers, two different costs, and two different right prices. Pile on that pre-owned stock depreciates the longer it sits, and a single blanket repricing rule will either overprice your rough units so they never sell, or underprice your clean ones and burn margin. This guide covers why used goods need condition-specific floors, how to reprice aging stock toward liquidation deliberately, and how to do it across a mixed used inventory without hand-pricing every item.
eBay condition tiers — new other, used, very good, good, acceptable — aren't cosmetic labels; they map to real differences in what a buyer will pay and what you can profitably accept. A "like new" unit competes against near-retail comps; an "acceptable" unit competes on being cheap. If you set one floor for the SKU, you'll price the rough unit as if it were clean (it sits forever) or the clean unit as if it were rough (it sells instantly at a loss of margin you could have kept). The fix is a separate floor per condition tier, each built from that unit's actual cost and the margin you need, so each listing competes only where it belongs.
Each used unit gets its own floor from its own cost basis. Worked example for the same model in two conditions:
Like-new unit — acquisition $40, refurb/cleaning $6, shipping $8, eBay FVF 13.25%, target margin 18%: Floor = (40 + 6 + 8) / (1 - 0.1325 - 0.18) = 54 / 0.6875 = $78.55 → $78.99
Acceptable unit — acquisition $18, minimal prep $2, shipping $8, same FVF, but a thinner 10% margin to move it: Floor = (18 + 2 + 8) / (1 - 0.1325 - 0.10) = 28 / 0.7675 = $36.48 → $36.99
Same model, two floors that differ by more than 2x — because the cost basis and the margin you'll accept are genuinely different. Undercut holds each listing to its own floor while beating its own comparable competitors.
Used goods have a clock on them. A unit that's sat 90 days is worth less than the day you listed it, and storage and tied-up cash have a cost too. The smart move is to plan the glide path: as a unit ages, you accept a thinner margin to move it — but never below the floor that still clears your hard costs. In practice that means setting a more aggressive repricing behavior on aging tiers so they press toward their (already lower) floor faster, while clean, fresh stock holds nearer market. The floor guarantees that even your most aggressive liquidation price still covers cost — you're trimming margin to move metal, not selling at a loss.
Hand-pricing every used unit by condition and age is exactly the kind of work that doesn't scale past a few dozen listings. With Undercut, you set each listing's floor once and, on Pro and Scale, set its aggressiveness: AI aggressiveness tuning lets aging-and-rough units move aggressively toward their floors while like-new stock stays conservative and holds near market — all running continuously without you touching it. As a unit ages, you raise its aggressiveness or lower its floor yourself. A reseller flipping a steady stream of mixed-condition used goods is the ideal case for automation, because the manual alternative is re-checking dozens of condition-and-age combinations by hand, every day, forever.

Can I use one price for all conditions of the same item?
You shouldn't. Different conditions have different cost bases and attract different buyers, so one price either overprices your rough units or underprices your clean ones. Give each condition tier its own floor and let it compete against comparable-condition listings.
How do I reprice used stock that isn't selling?
Plan a glide path: accept a thinner margin as the unit ages and set a more aggressive repricing behavior so it presses toward its floor faster. The floor still covers your hard costs, so you're trimming margin to move it — not selling at a loss.
Does the floor formula change for used items?
The formula is the same — cost + prep + shipping over one minus fees and margin — but the inputs differ per unit. Lower-tier units have lower acquisition costs and often a thinner accepted margin, which is exactly why each one needs its own floor.
Is automated repricing worth it for used inventory?
Especially so, because used inventory multiplies the variables — condition times age times competition. Hand-pricing that doesn't scale past a few dozen listings, while Undercut holds every condition-specific floor and reprices continuously on its own.
What plan handles different aggressiveness for mixed-condition inventory?
Any plan lets you set per-listing floors. Pro and Scale add AI aggressiveness tuning, so you can set aging or rough units to move aggressively toward their floors while like-new stock stays conservative near market — useful once your used inventory grows.
