RES LLC Store review for OCT Shipping Rates Calculator

Very good app that shows accurate shipping rate and estimated delivery date in the product and the cart page to my customers. I like the fact that customers can check shipping rates for everything they have in their cart when using the app from the cart page or for a single item when using it from the product page. I had some minor issues and support fixed them right away. This is a very unique app, I was not able to find other app with similar functionality.
