They ship all four of the dresses in a single priority delivery bag. They actually pack fairly tightly -- most of them are sheath and cocktail dresses, not "big ball gowns" (It's the style now, and I imagine they probably consider it for shipping cost reasons as well). The dresses get sent out three days before your rental starts, you have them for a few days, you send them back on the last day in the pre-stamped priority bag they provide. Shipping, altogether, is probably around $20, and the dresses are out of commission for likely 8 days in total, including dry-cleaning. So a rental for a $1200 dress might be $120, and if they're renting it out half the time (dresses are often unavailable in certain sizes/days because they keep things fairly densely rented), you can see how they'd make their money back pretty quickly.
