Do you preorder games?

In the UK if you pre order in a shop you don't have to pay until the day, so why not? You secure your copy in the chance they don't stock enough, get pre order bonuses and double points at GAME!

I always pre order

There's a nice GAME store very close to where I live. I've bought a couple of games there but turned down their membership offer. What do these points do?
