Buy a house, mail order!
In the USA, the mail order company Sears, Roebuck and Co used to sell kit houses (full size) by mail order. To avoid the obvious problems with the delivery address (no home for someone to be in at) the kit homes were delivered by railroad box car. I don't think Argos can top that.

Talking of topping, in 1973 the world's tallest building (Empire State, of course, in New York) was beaten by Sears Tower in Chicago.
