General merchandise is the catch-all department of liquidation. A GM pallet is whatever a returns desk, a backroom or a distribution center could not route to one department, so a box of kitchen gadgets sits next to phone cases, a carton of holiday lights and a stack of storage bins. That variety is the point. It is also why two GM pallets with the same manifest retail can resell very differently, and why the manifest matters more here than in single-category loads.
On most GM manifests a small number of lines carry a big share of the retail value. Open the manifest on the lot page, sort by highest retail first and read the top ten lines before anything else. Then ask one question: if the two most expensive items turn out broken or missing, does this lot still work at my price? The department breakdown at the top of the manifest shows where the retail sits, which tells you quickly whether a so-called GM load is really a pallet of small appliances or bedding with a few extras on top.
Unit counts swing widely with item size. A pallet of cables, cosmetics tools and kitchen utensils can hold hundreds of pieces, while one carrying storage furniture, a vacuum or an air mattress may hold a few dozen. Read the Units figure on the lot and divide your all-in cost by it. That per-unit number is the one a bin store lives on, because it decides whether a typical item can carry your opening-day price and still clear by the last markdown day.
GM is the backbone of bin-store inventory because the mix keeps people digging all week. The flip side is sorting labor. Every GM pallet needs a first pass that pulls out the items too big for a bin, the items worth listing on their own, anything with a dead battery or missing parts, and anything that cannot legally be resold at all. Budget that time before you bid, along with a dumpster or haul-away for the true trash.
Sellers offer GM as single pallets, multi-pallet lots and truckloads, plus the odd case lot. A single pallet is the cheapest way to learn how a seller's loads run before you commit to a truckload that has to move through your store in a week or two.
