Liquidators frequently sell goods by the pallet or truckload. A full pallet load is generally about 6 or 7 feet high and shrink-wrapped in plastic. Pallet loads usually sell for pennies on the dollars and can be a great way to get a wide variety of goods for a low price.
However, the drawback of buying in pallet loads is that they are often filled with a mixture of good stock and some not-so good stock that can be hard to resell.
