Guide
Most eBay sellers treat their price floor as a fixed number. That's a mistake. Seasonal demand reshapes what buyers will pay — and what the lowest competitor will dare to list. The smart move isn't chasing the floor down in January when holiday stock oversupply hits; it's holding firm off-season and raising your floor proactively before peak season begins. This guide walks through exactly how to set, adjust, and automate seasonal floors so Undercut does the repricing without ever selling you into a loss.
Demand elasticity on eBay shifts dramatically by time of year. When 40 sellers flood the platform with Christmas ornaments in February, the race to the bottom is tempting — but it destroys margin on inventory that would sell at full price by October. Conversely, a seller who holds a firm floor in February keeps margin intact and moves units profitably once demand returns. The same logic runs in reverse for summer outdoor goods, back-to-school supplies, or Valentine's gifts: as the peak window approaches, buyers tolerate higher prices and competitors haven't yet undercut each other into the floor. Seasonal repricing is therefore a two-lever system: raise the floor before peak demand arrives, and hold — not lower — the floor as the off-season sets in.
Take a Halloween costume accessory: landed cost $8, average shipping $4, eBay fees approximately 13.25% of sale price, target minimum margin 15%. Working backward: floor = (cost + shipping) / (1 - fees% - margin%) = ($8 + $4) / (1 - 0.1325 - 0.15) = $12 / 0.7175 ≈ $16.72, rounded to $17.00 as your year-round hard floor. Now apply seasonal logic. In September and October, buyer demand is at its highest and competing listings thin out as stock sells through. You can responsibly raise that floor to $21–$23 — not as a guess, but because completed eBay sales data from the prior year shows average selling prices 25–35% above February lows for the same item. In November, oversupply hits post-Halloween clearance. Rather than dropping to $10 to 'move units,' hold $17. The unit either sells at margin or sits until next September. Dumping inventory at $10 books a confirmed loss; holding books an unrealized wait.
Not every category follows the same calendar. Understanding your category's demand curve is the prerequisite to setting seasonal floors intelligently.
Manually updating floors across hundreds of listings before every seasonal shift is error-prone and time-consuming. Undercut lets you set a hard floor per listing — a number the repricer will never breach regardless of what competitors do. When your peak season arrives, you raise each listing's Floor Price in the dashboard; Undercut then auto-undercuts the new lowest competitor price, but only down to your revised, higher floor, so a higher floor effectively holds your price up during peak demand. On Pro and Scale plans, the 15-minute repricing interval means that when a competitor sells through their last unit and prices spike, Undercut responds within minutes — not hours. The AI aggressiveness tuning on Pro and Scale lets you set, per listing, how fast and how far the listing moves down toward that floor, which is particularly valuable in fast-moving seasonal windows where prices can swing $5–$10 in a single afternoon.
The most damaging mistake is treating the repricer as a race-to-the-bottom engine with no floor. Without a hard floor, automated repricing during an off-season oversupply event can drain margin to zero — or below — across hundreds of SKUs before the seller notices. The second mistake is setting floors once and forgetting them. A floor calculated on last year's COGS is wrong the moment your supplier raises prices. Build a quarterly floor review into your workflow, especially before each major seasonal transition. Third, sellers often lower floors proactively ahead of a slow season 'to stay competitive.' The data rarely supports this: conversion rates on eBay for seasonal items drop because buyer intent drops, not because prices are too high. Protecting your floor in slow periods preserves both margin and the perceived value of your listings.

Start freeHow far in advance should I raise my seasonal floor before peak demand hits?
Four to six weeks is the typical lead time. Competitor prices start rising 3–4 weeks before peak as sellers anticipate demand, and raising your floor at week 6 means Undercut is already positioned to undercut those rising competitors at a profitable price — rather than catching up after the window has partially closed.
What happens if I hold my floor and don't sell through my off-season inventory?
Unsold inventory at margin is a storage cost problem, not a pricing problem. If your off-season floor is correctly calculated to cover cost plus fees plus a minimum margin, holding it means you either sell profitably or carry the item until the next peak. Selling below the floor books a confirmed loss; carrying the item does not.
Can I set different floors for different seasons on the same SKU in Undercut?
Undercut stores one active floor per listing at any time, which you update in the dashboard whenever you want to change it. The practical workflow is to keep your seasonal floor calculations in your own spreadsheet and update each listing's Floor Price before a major season transition. The repricer immediately respects the new floor.
My category has unpredictable spikes — a viral moment or a news event. How does seasonal floor logic apply?
Event-driven spikes behave like compressed seasonal peaks. The floor logic is identical: raise your floor to reflect elevated demand willingness, let Undercut undercut the new competitor landscape at that higher floor, and hold the floor as the spike subsides rather than chasing the market back down. The 15-minute repricing interval on Pro and Scale is particularly useful here, recapturing position within one cycle as competitors move.
Does Undercut automatically detect seasonal patterns and adjust my floors?
No — and this is intentional. Floors are a seller decision because they encode your actual cost basis, which only you know. Undercut enforces whatever floor you set with precision and reprices competitively above it, but it does not move your floor autonomously. You control the floor; Undercut controls the competitive response above it.
