Toolify Shipping Rate Manager

Excellent CSV uploading tool for shipping rates (from shipping providers that don't integrate with Shopify). Saves me hours and hours of my time! Let excel do the tedious copying work instead of entering shipping rates line by line. I highly recommend it. Just learn the ins and outs of how it should work (i.e. how to prepare the CSV file) and then start uploading.

The customer support was excellent and fast too. I ran into a problem during an upload and the issue was sorted immediately.
