Pet cost-per-unit trend

Each point is the monthly median cost-per-unit across priced pet lots — the middle value, not an average, so one outlier truckload can’t drag the line. A live lot counts in the month it first appeared in the feed; an ended lot counts in the month it closed. Lots match the category by their title — the same category match the live feed uses — and cost per unit is the lot’s price divided by its listed unit count, where the source publishes one.

Months with fewer than 30 priced lots render as insufficient data and stay off the chart — a median over a handful of lots isn’t trustworthy. That floor gates the chart, the “Months with data” stat, and the month table above alike.

The lots behind the series come from the nine marketplaces BStalker scans: Liquidation.com, B-Stock, DirectLiquidation, 888 Lots, Via Trading, BlueLots, GovDeals, Musick, and QuickBidz. Sitewide medians, discount-vs-retail, and closing-time patterns are on the statistics page.

Pet lots cover beds, crates, aquariums, carriers, and accessories — durable goods that tolerate returns well, plus consumables where dating matters. Big-box and specialty-retail returns feed the volume. Manifests list the item mix; hard goods carry the resale value while consumables need date checks.

Pet per-unit is driven by the hard-goods-vs-consumables split in the manifest. BStalker shows the per-unit number; the mix on the manifest tells you what you are actually buying.

What goes into a per-unit number — bids, buyer premiums, freight — is covered in liquidation pallet costs explained, and the live lots themselves are on the pet lots page.
