It's funny that you bring this up now because back when BB10 started airing, I started looking for, after years of swearing to myself I never would buy BB on DVD, the BB3 DVD set--but the Amazon price was outrageous, and even eBay auctions went for a pretty sizable amount. (And from what I read about the cases, online ordering would be a bit risky anyway.) No B&Ms carried it, and all indications were that it would cost a lot from them too. But as luck would have it, in August I found a used copy for $20 at Fye. I've barely started it but it is cool to look back and remember how big a crush I had on Lisa and how annoying Josh was.
I could never agree that it's the best reality show, and I might do the unthinkable and only purchase select seasons--I have no desire to see BB4 or 9 again--but Amazon.com's burn-on-demand feature is made for shows like this. I really can't believe they haven't explored this, Survivor, Amazing Race, Apprentice, etc. for burn-on-demand.
