makinglifebetter.com. I have found country crock, wishbone, breyers, degree, dove, etc. all here. Plus there is a section for samples as well. And best of all it is all in one place.
You do have to sign up which means sharing personal information. I feel kind of weird about putting my birthdate in, so just created an alternative birthday that I share with companies. And if it doesn't have a star next to it I don't fill it in. That way I'm not giving out any more info than I have to.
