What's the "biggest" thing you've bought online?
Biggest, most expensive, or however you want to define it.
I've ordered a laptop before, and a flat panel TV. Had to sign for the laptop, but not the TV.
I would never buy something like a sofa, though. I need to see it, sit on it to judge the comfort, etc. I can't imagine the hassle of getting it, but not liking it, and then having to return it.
