Thought I'd give it a try but didn't expect much. I've used it for 2 days and thus far saved about $50-75! Several items I got a $20 discount on, one of those I purchased on Ebay because it was $20 cheaper than Amazon. Amazon is my go to for purchases. I used to check with several other sites to be sure I was getting the best price [Walmart, Best Buy, Ebay] and it would appear that this app does that comparison for me....that's a lot of time saved. So we shall see over time, but right now I'm lovin' it. Hopefully I can come back and update my review later....
