Use the Mobius link to go to Amazon.com. When there, click on DVDs and the sale should pop up. There are a LOT of sets on sale from the early days of television to contemporary fare. However, the emphasis seems to be on older shows.

There is one sale on Warner titles and another one on Classic TV. The easiest way to find a link to the Classic TV sale is go to one of the listings for Perry Mason or Mission Impossible sets and you should see a link below the description.

There may also be a similar sale going on at amazon.uk. I was able to get the new PRISONER set for half price.

See also deepdiscount.com, where you can get THE ADVENTURES OF BRISCO COUNTY for a mere $25 [it's $72 at amazon].

I just ordered that several days ago. I stumbled across it by chance while looking for something else on DDD's site, and just about fell out of my chair. I've almost ordered it a couple of times during their semiannual 20% off sales, but I'm glad I held off until now.
