Super Plugin and super support.

I was looking for a plugin which helps me to calculation the price per kilometor or per miles. I found this one, but was facing issue with API (that was my mistake that created wrong API). Then i contacted to support and they really replied me within 24 hrs, and also helps me to setup the Prop API. Strongly recommended this plugin who is looking for shipping cost base on distance or distance based shipping charges or fee.

really amazing.
