I love using coupons and there is a place online where you can sign up and receive great coupons for Rent A Car enterprise coupon.
ebates works will tons of stores that you purchase from. Work from the ebates website, find a store you want to purchase from and you receive cash for a percentage of your purchase. I just did a purchase at TigerDirect and received 3% cash back on my total purchase! I love money in my pocket and everyone could use some today.
