Did all my purchases just now. Its too bad for my final purchase, since my gift card didn't cover it it charged me the full amount (and now I have a small amount on my gift card which probably won't be used for a very long time...)
Ended up spending over $100, but got 11 games and 4-5 DLCs, not too bad. Half the games I bought weren't even on sale, but I bought them anyway since they are going away forever whenever they shut it down tomorrow (XBLA non-BC exclusives that never made it to disc).
