The Bits du Jour web site offers one discounted item per day (2 on Tuesdays and Thursdays) -- either Windows software or a web service. You can see the upcoming deals, and download a trial version, to see if it's worth buying when the discount day arrives. You can also read comments from other users, which might alert you to any problems or questions about a specific product.
The products are ordered directly from the vendor, so you're buying the full, current version of the product, not a limited version. The products appear to be downloads, so those of us who are outside of the USA shouldn't have to worry about shipping problems.
A quick visit to the site, once a week, will keep you up to date, and then you can return if you've decide to buy something, on the day it's offered.
