Here's one of my frugal tips:
At the beginning of the month, go to Walgreens and pick up an Easy Saver Catalog. It is filled with coupons and rebates, and always has a bunch of items that you can get for free after the mail-in-rebate.
I seriously get so much free toothpaste, shampoo, makeup, etc. each month that I hardly ever have to buy it.
You can thank me later :-)
