DEAD: 25% Cash Back From Live.com for Drugstore.com Purchases

Update, 12/31: They've pulled this offer, at least for the time being, sorry!
This has been around for a few weeks but I want to mention it here because, in combination with Drugstore.com's after-Christmas sale, 25% cashback is pretty sweet.

Go to http://www.Live.com and search for Advil. It'll bring up a sponsored link for Live cashback (look for the gold coin). Click through and provide your email address and the CAPTCHA image, and you'll be on your way to receiving 25% cash back on your Drugstore.com purchase. (Nope, you don't have to even purchase Advil at all -- anything you buy in the 60 minute time-frame after clicking through the sponsored link will be eligible for 25% cash back.)

Be sure to check the End of Season Up to 70% Off Clearance banner to see some of the more highly discounted products.

Lesser-known tip: If you have a flexible spending account (aka a medical savings account -- pre-tax dollars set aside for non-insurance-covered medical expenses) and you access it via a debit type card, you can shop through a rewards program like Live cashback and earn 25% cash back on those pre-tax dollars! Look for items on Drugstore.com's website marked with a blue check and the letters "FSA," and use your FSA debit card for your payment type!
