Promo Codes

What am I supposed to do with these? I know they get you free stuff with EA games but it doesn't tell you where to enter them or anything. Please help?

why cant i log in to origin to get my slim jim code it keeps saying thaht wasnt suppoed to happen

i'm unable to login to my account on here, is there an issue with the site or is it just me? if it's just me please help. i'm constantly seeing "woah, that's not supposed to happen" and returned to home page and this strted this whole day i even used my friend's iphone.

I'm also having this problem. I know my login works for Origin, but even after I added a code, I can't sign in to use my codes for MOH: Warfighter (and for Dead Space 3, with I have pre-ordered.

I entered 10 slimjim promo codes and was planning on using them for the Dead Space 3 content, but when I logged in today to enter more- it said I only had 1 code?  How can I restore those codes for the Dead Space 3 content?  I have the confirmation #s for 8 of the 10.

The exact same thing happened to me

Thanks for the help. I wonder if anyone else would know how the codes work for the Slim Jim promo then.

I feel really dumb now because it was just my computer being dumb. It finally worked on the website. Sorry about the unnecessary post!

I was wondering if or when the content catalog for EA slim jim would be updated. I have codes too use but there's no new  updated content.
