Places that do a lot of mail order pay much less for postage than you as a member of the public do.
Back when JE was in Bury I worked out that it was still cost effective for me to have them mail to me rather than collect from the store. Postage was way less than the petrol to get there.

Actually I remember the JE staff saying that Ebay brought in much of their business and was vitally important to them - so they must have been making some money on it!
