I discovered this site recently and have bookmarked it to locate useful coupons (both online and in-store) whenever a shopping need arises. I especially like that you can sort by store names if need be.
Also, I discovered this freebie website not too long ago and although it technically says, "Freebies 4 Moms,"you don't have to me a mother to enjoy the site. Currently, there is a free sample of Starbucks coffee (by mail) offered. And you know I love me some free coffee.
