Figured it out I think. best Buy's website for some reason doesn't mesh with the boards here and can't be linked to. So anyway, just go to their website and to the weekly ad section and there's a huge HBO sale. I got Eastbound & Down seasons 1 & 2 Blu-Rays for $15 each, and season 3 for $17. Seasons 1 and 2 Blu-rays of Boardwalk Empire for $32 and $29 each, respectively, and Curb Your Enthusiasm seasons 7 and 8 DVDs (finally caught up on all of them now) for $15 each. They had The Wire The Complete Series for $90, but I got it for $10 cheaper at Target, plus an additional 5% off for using my Target credit card.
WBshop.com (<-that's a fucking link. Boards are still wonky on coloring hyperlinked words, it seems) has a pretty swell Adult Swim sale right now. Tons of stuff for $9.99. Passed on all these for now at least; spent enough on the HBO stuff.
