FABLE 2 limited edition content help

okay so i got fable 2 limited edition today, brand new in the shrink wrap from this store, not sure what to call it, they sell lots of electronics and stuff real cheap, its legit, usualy its returned items they buy from other stores or stuff the stores cant sell crap like that, and there is no card thing i read about online to get my dlc, and my reciept says electronics - 19.99, no mention of it being fable 2 limited edition, so how on earth do i get my code for the extra stuff, this place has no returns no exchanges all sales final, and i already bought fable 2 once then sold it so now i want the lec stuff :( anyone know what i can do?

buy a code off ebay or complain. I would complain as the only good thing about the special edition is the extra content, not the extremely crappy extra disk. God i hate the contents of that disk, i just wanna burn it.

What exactly is on this limited edition game?

I downloaded the bonus content from the market place and I was wondering if it's the same thing or not.

It's perfectly fair for Microsoft to add the dungeon and armor in the limited edition otherwise the Limited Edition was pretty much worthless.
