Copper review for MT Table Rates Shipping

This seemed like the easiest way to get our custom shipping rates into shopify by zip code. I ran into issues implementing the app and after trying everything I still could not figure out the issue. The developer was very communicative and finally figured out that my google sheets csv export was adding spaces for where they didn't exist. So we created a new spreadsheet and ran the same csv through a couple imports and exports and it worked. Strange. The developer was a HUGE help and now everything is up and running smoothly. Thanks MT Table Rates!
