Would be an awesome deal for Buffy, but I already own a Buffy box set (though I paid about $85ish at at a Sam's Club a few years ago)... Granted one of the disks in season 6 was bad, and I never went back to watch the rest of the episodes in order because of it(got to that disk several months after I bought it, so it was far too late to be able to return it any longer...).
Might be tempted on the Angel one since I'm currently watching it through Netflix, and I would like to actually own it as well...
