Hair detangler for DD, I simply put a few drops of conditioner (free from samples

) in the bottle with warm water and shake. It works just as well and costs virtually nothing.
JetDry, vinegar works just as well for pennies.
Stamps, I pay my bills online. I think I only mail about 2 checks per month at this rate.
Deodorant, shampoo, razors, toothpaste, Alavert. I get them for free using coupons, samples or at CVS (using their Extra Care Bucks promotions)
