Not perfect but it's saved me a lot of money $111.97 on my order from mypillow.com alone! You won't save money every time but it's very helpful in those times where it finds coupons. If you're like me and are worried about someone tracking your browsing history only activate it when you're browsing stuff to buy. I don't know why people are leaving 1 star reviews just to say honey tracks you when there's no evidence that the company uses it for sketchy purposes and like I typed before just inactivate honey when you don't use it. The only problem I've had is sometimes when it uses multiple codes the website will refresh over and over again but i've never had wait more than 3 to 4ish minutes.
