Kraft First Taste is community launched by Kraft a couple of years ago were you get to try their new products most of the time free (with coupons send via snail mail or printables), you can write your opinion and discuss various topics with other member. If you are interested in participating you can Sign Up here.
The more you participate , the more chances you get to get a free coupon offer otherwise you might only get a coupon with a high discount of the product.
Right now they are offering a coupon for a free Philadelphia Cooking Creme (up to $4.49), if you are just singing up you might not get this offer, but they are always sending invitations to try new products.
