Savings Guard completely automates the process of finding the best savings for you with the simple click of a button. When entering a shopping cart page on a supported e-commerce website, Savings Guard will pop up in the upper right hand corner of the browser window whenever coupon codes can be applied. Clicking the "Find Coupons" button will cause it to search through a number of available coupons and automatically apply the one(s) that will save you the most money. It will save you the time and trouble of having to manually select and try out codes individually.
