How Often Do You Preorder?

[BluPix]

How often do you preorder titles that haven't yet been released (from Amazon.com or other stores)?

For me, it depends on how much I like the title and the price. I've often seen prices drop within a few months (if not days) after the item is released (after it was already sent to me at the higher price), but I've also seen prices rise after I placed the preorder, but before the item is released, thus actually saving money.

Lately I've been wanting to preorder much less often, because prices tend to be the same, if not a little better, later on. What do you think?
