OK, just got back. They did credit me $22 back on my credit card so my total came to about $25+tax per season.
There does appear to be some sort of SKU issue though. The season sets that go on sale for $34.95 don't actually hit the shelves until tomorrow. These sets come in the newer, slimmer packaging and only come with 6 DVDs each (the online description is wrong, the printed flyer is correct).
The sets I picked up were the older ones that come with 7 DVDs each. The seventh disk is the extra features and stuff. I'm not sure if they've condensed the seventh disk onto one of the other CDs for the newer sets, but if you're picking up sets, it might be better to grab the older boxed set if they still have it at your local BB. Just make sure it rings up properly at the register.
