We never sell by weight or as surprise lots. Each lot states how many garments it holds, their category and brand tier, their condition and the price per garment.
A bale sold by the kilo comes sealed, with no guarantee of brands, sizes or condition, and part of it cannot be sold. With a lot sold per garment you know what you buy and can work out your margin first. The comparison, with numbers, is in Buying wholesale clothing: by the kilo or per garment.
