FINALLY found a copy of S4. I went to BestBuy on 10/24 and they were sold out. And they didn't have it on subsequent visits. I went to Target by chance for something else last night and they had one lone copy. Was there a distribution problem with this set for some reason?? Oh well--at least we're halfway done at last. I wish they'd speed up the delivery of the last four seasons so we can them all in 2007.
