I love this extension! It makes shopping so much easier. I wish I could give it more than five stars. I highly recommend it !!!!

I only wish I had this sooner! The algorithm is very cohesive and the platform is very user friendly. I could've easily saved a lot of money over the years had I been doing what this app does FOR YOU. Very nicely done.
