I just use netflix for my blu-rays/hd-dvds. Not cheap enough to buy out-right ( for me yet ). Netflix has a pretty good selection of both. It doesn't cost any more extra than the regular DVD plan. As far as cheapest place locally, it just depends. Fry's usually will be pretty close to the cheapest, but they're all within a $1/2 of each other, except Blockbuster (buying them new), they're just ridiculously expensive.
