While making packages smaller is perfectly legal, the purpose behind

Not always. WalMart rags on its suppliers to reduce package size, thereby
reducing shipping and stocking costs. Walmart also complains about items
that are double or triple wrapped when single wrapping would do.

For example, we've all seen boxes labeled "Box may not be full due to
settling in shipment." Walmart, and others, say " 'Settle' the stuff before
you package it and use a smaller box."
