I've seen GD:RB at my Walmart for $20 a few weeks ago, but it was definitely the regular edition (which requires the $10(I think) fee to export).
However, I have seen a commercial for their new album (w/e it is, idk, not a huge fan), and at the end of the commercial, it said something to the effect of, "And be sure to get GD:RB, now at a reduced price of $20!" (It did not specify a retailer, and I believe it was the regular edition).
So in conclusion, it may be just your local Wally World, or it may be for everybody. Need more data!
