I am wondering specifically for Desperate Housewives. I own both seasons 1 and 2 of the series, and am missing disc 3 of each. I have been thinking of buying both DVD sets again, but that seems to be a waste of money when it's really only the one disc that I need. There is also the option of downloading the missing episodes on iTunes, but then I won't get the special features that come on those particular discs. Any ideas? Thanks so much. Someone told me that I could do that on www.dvdsetshop.com. Does it work?
