After a month of waiting, I finally received my code for Grunty via email!
I applied my code and received my [The Marine Marine] achievement on all characters after I logged them in and looted the egg!
It’s funny to think that people would buy the Grunty code from the Blizzcon ’09 goodie bag (from Ebay) for almost $100. If they were patient then all folks had to do was buy the $40 stream service and save a load of money. The current ’email’ codes seem to be going for $20-30 on Ebay.
