Fable 2 pre-order deal?

I was wondering about the pre-order deal, where you get the pub games for free in august.

Let's say I pre-ordered the game at the participating retailers, how would they know I bought it so I could claim the free pub-games? I'm not too keen on this, I've never done this kind of deal before.

So could someone please explain to me how it works?

you know when you buy the game when it comes the pub games will come with the game for free...so do they say you will get free pub games on august if you preorder?

anyway i heard gamespot was giving out promotion codes or something...

theres a similar thread type in Fable 2: Pub Games

Still doesn't answer my question =\

When I pre-order from like amazon.com, will they send my account some sort of redeem key or something so that I could claim the pub games for free?

I hope Amazon is in on this deal. They had a price mistake like 6-8 months ago on Fable 2 at $49. I got in a preorder. If they also offer me the pub games, that will make the deal even sweater. If not, than I'd have to pay the $10 to get the games on XBLA. Then I might as well cancel the Amazon order and get it locally so I can have the full game, in hand, on release day.
