I forgot they sent me free samples of formula as well close to my due date. When I started formula feeding it was nice because I had different kinds and found a good one that worked with baby :)
If you are looking for formula and bottles Similac and Gerber if you sign up they will send good coupons for both and send you free bottles but it will be closer to your due date and after baby is born. I don't know about other items like clothes or furniture..for me I have always been into buying used either at garage sales or second hand stores. Babies grow so fast these things are hardly used. Buying used has saved us tons of money!
