Sneaky Ways to Save Big by Mary Hunt
Shop till you drop
A new breed of shoppers arm themselves with coupon codes and rebates, then find a way to layer deal upon deal in a tactic called "triple dipping."
Here's how it works: Go online and find the cheapest price on the item you're looking for. (Use a shopping bot or comparison search engine like froogle.com or mybargainbuddy.com) .... Then search for a coupon code that will effectively drop the price even further. Pay with a credit card that gives you cash back, miles or some other reward.
