They shipped UPS. Some 21” models were too heavy and required freight or some expensive service. They’d be in a big box with foam and mostly ship fine. People

They shipped UPS. Some 21” models were too heavy and required freight or some expensive service. They’d be in a big box with foam and mostly ship fine. People weren’t ordering individual rolls of toilet paper online then, so you weren’t getting killed on dimensional weight like today. At a store, iirc, we’d get anywhere from 18-24 displays on a pallet, depending on size. The original iMac shipped 9 to a pallet iirc.
