Tell me: do you pre-order books?

Exciting moment #29 (or something like that) in this newbie author journey: realizing you can pre-order Double Vision.

And I'm a bargain at B&N, check it out. But who really cares but me and my writerly friends, right? I know I don't pre-order books much more than a week or two in advance, if at all.

Which got me wondering: do you pre-order books? And if so, how far ahead of publication?

I'm curious.
