I have joined a few clubs lately that send lots of free samples, coupons, and coupons for free samples. They don't send lots of emails or bother you very much at all, other than to give you free stuff. Give them a try; I have really enjoyed them.
Vocalpoint: Things I've gotten recently are: free Crest toothpaste and Delmote fruit naturals. I also received coupons for these products to give to friends plus I've gotten high value coupons for Venus razors and Kashi cereal bars.
SheSpeaks: Recently, I receive a cute little box with five Ghiradelli chocolate peanut butter squares with five coupons to go with it. They were delicious
Kraft First Tastes: Just joined so I'll have to let you know!
Psst...: I received high value coupons for Progress soup, Yoplait yogurt, Macaroni Grill Dinner kits, and free Pillsbury frozen cinnamon rolls.
