Oh I didn't realize if unopened there was no restocking fee. There's little risk to ordering it now then and just watching for deals before Black Friday. I'll give it a day more and then definitely order the drives. They're great quality drives at an excellent price, so I don't think I'll be sorry no matter what. Well maybe finding good quality 12TB drives at the same price would hurt a bit, but not too much!
Now, if I can resist not starting to fill them up when they come for 30 days... I've got at least 500 DVDs of movie and TV series that I decided I wanted to put onto hard drives for streaming. It's become a real bother to actually dig through my multiple binders full of DVDs to find what I want, even though I have a decent catalog of everything. There's nothing like just pointing to the movie and streaming it from your TV without getting up, I've gotten really spoiled.
PS: Thanks for helping me spend my money!
