Guide
Electronics depreciate faster than almost any other eBay category. A graphics card that listed at $320 in January can be worth $240 by March. That price decay is relentless — and if you are manually checking comps once a week, you are already behind. The fix is not just repricing fast; it is repricing with a hard floor so that as the market drops, you follow it down to a win without selling below your actual cost. This guide walks through exactly how to do that, with real numbers.
Most eBay categories have stable or slowly shifting prices. Electronics do not. GPU prices swing on new-release announcements. Refurbished iPhone pricing moves within days of a carrier promotion. Opened-box laptops depreciate the moment a newer SKU ships. This means two things for sellers: first, you can capture a sale quickly by being even $1 below the lowest live competitor. Second, if you do not update prices constantly, you are either overpriced and invisible, or underpriced and bleeding margin. The solution is automated repricing with a floor — not just a floor in your head, but a hard number locked to each listing that the repricer will never cross.
Your floor is the lowest price at which selling the item is still worth it. For electronics, that calculation needs to account for cost of goods, shipping (often heavier than other categories), eBay fees, and your minimum acceptable margin. Here is a worked example for a refurbished tablet:
Cost of goods: $62.00 Shipping (box + padding + label): $9.50 eBay final value fee: 13.25% of sale price Minimum margin target: 15%
Floor = (Cost + Shipping) / (1 - FVF% - Margin%) = (62 + 9.50) / (1 - 0.1325 - 0.15) = 71.50 / 0.7175 = $99.65
Round up to $99.99 and that is your floor. Undercut will reprice that listing down to $99.99 to beat any competitor, but it will never go to $98, $95, or $89 chasing a race to the bottom. You win the sale or you do not — but you never sell at a loss.
Repricing once a day is fine for books or clothing. For electronics, it is often not enough. A competitor can drop their price, take your sales for 18 hours, and restock before you ever notice. The faster your repricing cycle, the more time your listing spends at or near the top of search results. Undercut's Pro and Scale plans both reprice every 15 minutes — the difference between them is capacity, not speed. For high-volume electronics sellers — especially those moving phones, tablets, or gaming hardware — Scale's 10,000-listing capacity and priority support keep a large, fast-moving catalog covered at the same 15-minute cadence. If you are just starting out, the free plan (25 listings, repriced multiple times daily) is enough to learn the system before committing.
Not every electronics listing should chase the floor aggressively. A brand-new, sealed-in-box item with high demand should stay near market price — dropping fast only trains buyers to wait for a lower price. A refurbished unit with 90 days of shelf age and three competitors actively undercutting each other is a different situation: you want to be at the floor as soon as possible to move the unit before it depreciates further. Undercut's AI aggressiveness tuning (available on Pro and Scale) lets you configure, per listing, how quickly and how far a listing moves toward its floor. You can set a refurbished unit to move aggressively toward its floor while a sealed-new unit moves conservatively. This is especially useful for mixed electronics inventories where the same repricing behavior should not apply across every condition level.
The most common error is setting no floor at all and letting the repricer match any competitor price. In electronics, this is dangerous because some listings are priced incorrectly by sellers who made a calculation mistake — and your repricer will match them straight into a loss. The second most common mistake is setting a floor based on the original purchase price without accounting for eBay fees, shipping, and return risk. The floor feels safe but is actually below breakeven once you run the math. The third mistake is repricing too infrequently in a category where prices move hourly. If your repricing cycle is 24 hours, you are likely winning sales only during the window right after the cycle runs, then drifting out of position for most of the day.

What happens when every competitor drops below my floor?
Undercut holds your listing at the floor price rather than crossing it. You may lose the sale, but you will not sell at a loss. At that point the real question is whether your floor is correctly calculated or whether the market has structurally moved and you need to reassess cost, bundling, or liquidation options.
How often should I update floors for electronics listings?
At minimum once a month. For fast-depreciating categories like smartphones or GPUs, review floors every two to three weeks. If you change shipping carriers, update immediately — a $2 shipping cost increase directly raises your breakeven floor.
Can I set different repricing aggressiveness for new versus refurbished condition?
Yes. On the Pro and Scale plans, Undercut's AI aggressiveness tuning lets you set a different aggressiveness on each listing. A common setup is conservative repricing on your sealed-new electronics and aggressive repricing on the refurbished or open-box units that are aging on the shelf.
Does Undercut reprice multi-variation electronics listings (e.g. different storage sizes)?
Yes. Each variation can carry its own floor, so a 128GB and a 256GB model of the same phone are repriced independently against their respective competitors — not blended together.
Is the 14-day trial enough time to see real results for electronics repricing?
For most sellers, yes. Electronics categories have enough price movement that within 14 days you will see the repricer actively adjusting listings, and you can compare how quickly your items sell and your average selling price before and after. No card is required to start.
