Borderlands - Gearbox Mercenary weapon pack?

I know if you order (or pre-ordered?) this game from Gamestop or Play.com, you receive a weapon pack consisting of 8 guns.

Can anybody confirm whether this weapon pack is included on the disc, a one-use code or one code that can be re-used? Thanks.

It is 8 custom weapons each class gets 2 of them, Its packed in the game and is a one time use code.

Thanks for reminding me. Is it already pre installed in the disk? The guy at Gamestop told me it would be in the case but it wasn't. I guess I was a little too excited about playing the actual game and forgot all about the guns, and I'm most likely too high a level for them now so it still doesn't matter but... I still wanna know if I can put the code in, especially if it's weapon skins.

Theres a slip behind your instuction booklet with a code.

FYI the guns are completely usless.

Great, I guess I won't worry about it then.

The guns are not useless, all of them will last you 3-4 levels.

I replaced them before I could use them. And those 3 or 4 levels go by in about 20 minutes anyway.
