I just called a local GameRush, and the guy said that the deal will be coming back, but they don't know the date yet. Another interesting thing for people in my area (St. Petersburg/Clearwater, FL) - the guy said that starting October 15, ALL Blockbusters will be taking trades around here. He said that they worked out some deal with the local authorities to relax the pawnshop law for game trading. Here's hoping the thumbprint/trade sheet are a thing of the past, too.
I know that GR generally sucks, but if the DO have something in stock that you want, the trade 3 deal and generally higher trade values make it a better deal than EB/GS.
I'm going to post this in the sticky thread too.
