Wow, I got in on this but in a completely different way. I didn't realize Just Dance 2 had anything to do with it: I thought it was all about the MJ game. Well, in any case, that is all that worked online last night when I put in store pickup orders (by the way, there was a very lightly viewed thread about this). Both Epic Mickey and DKCR were OOS online and not available for store pickup anyway so that's why they weren't mentioned in the other thread.
I did put in an order for Just Dance 2 - but just for the game by itself for $20. Had I known it would have halved another game I would have used that instead of the MJ game.
So today I picked up my orders but then also got MJ + Epic Mickey and MJ + DKCR in store and it worked just fine on both of those two. But then after doing some shopping I tried to get MJ + Flingsmash which had worked fine online the night before and it didn't work. So I assumed they corrected the glitch around 6pm Pacific. Turns out maybe I was wrong - yet those two rang up at $75 together and that had definitely worked online before.
I also wish I knew about the Epic Mickey CE because I'm pretty sure I tried that online last night and it
did not work then.
In any case, I was happy to get Epic Mickey, DKCR, and Flingsmash all for $25 each (as well as GoldenEye w/gold controller for $35!). I had wanted a second Flingsmash so I could upgrade all my old Wii remotes, but it's no big deal...
This was kind of sort of one of the best deals of the year and I think most of CAG missed out on it
