Easy and fast to set up price alerts on Amazon and Walmart. Saved $20 on products on my wishlist. Price history charts are nice too.

Game changer for online shopping and if you like saving $$$. I've been using the service for Amazon for a while and already saved a couple hundred bucks during Black Friday week. Even more awesome now that they support a lot more places like Costco and Walmart.

Great resource for finding discounts! It even syncs with your amazon wishlist
