I started playing around with this 4 weeks ago. I used the link to go into drugstore.com and order things I would normally get at the grocery store. To my surprise the prices at drugstore.com were cheaper than the grocery store. I got free shipping due to the size of my orders and in 2 transactions I made $23.54 with extrabux and an additional $13.86 in drugstore.com credits. This is definitely worth looking into. You can shop at 2000 different stores! I'm impressed!
