Who likes free baby samples? What have you found?

Ok, so I am a mom to be who is on a very limited income at the moment and even when I am not on a limited income, I like to get a good savings. But who doesn't? I hav found that Similac, Gerber, and Enfamil all offer samples with bags for the hospital. Parents Choice (walmart brand) sent me a full day supply of infant formula in the mail. So my question to you all is have you found any recent good, tried and true, samples or coupons on the web? Formula, baby food, toys, wipes, diapers, whatever! I know if you are like me, you are probably just surfing the web for good deals until the little one comes along! (Oh and last I check Walmart had diaper wipers-their brand) for .98 cents. I picked up ten and made quite the savings!
