Pre-ordering FM

I tried to use this code 'GMGFM-C7BEY-U0PMY' that I got emailed last week and it didn't get me the discount on greenmangaming, it said the code was invalid. Am I doing something wrong? I also tried to do it through sortitoutsi and that also said the discount code was invalid.

Cheers,
Dan

Was the code you were emailed from greenmangaming specifically? Assuming you've already tried entering the code without hyphens, swapping the 0's for O's and all that stuff its probably something you'll have to take up with whoever supplied you with the code. Also maybe not such a great idea posting it publicly incase someone goes and steals it.
