The first pallet is the one people get wrong, almost always for the same two reasons. Neither has anything to do with which load they picked.
A pallet is roughly four feet by four feet and can stand chest high. It arrives on a truck, not in a van, and the driver needs somewhere to set it down. People buy before they have thought about this and then find themselves unloading a pallet by hand onto a driveway in the rain.
Work out your unloading before you order. A dock or a forklift is easiest. If you have neither, ask for a liftgate and it will be lowered to the ground for you at no charge. Then work out where it goes after that, because you will need floor space to sort it.
The temptation is to multiply an approximate unit count by what those units sell for new and decide the load is a bargain. That number is fiction. It assumes everything works, everything is complete, everything sells, and it sells at full price.
This is exactly why we publish no retail values and no expected resale figures. Price your first load against what you can realistically list and ship in a month, not against a retail multiple.
The condition basis tells you far more about how a load will perform than the department does. A shelf-pull load of tools and a returns load of tools behave completely differently. Read the load details block on the listing, which states the basis in plain words.
Then keep a note of what the load cost you per sellable unit once you had sorted it. That figure, not the headline price, is what tells you whether to buy the next one.
