Small Kohana module to calculate USPS shipping rategithub.com/kureikain1 pointkureikain14 years agoA very small, buggy but lovely Kohana module to calculate shipping rate for USPS. It supports both of JSON and JSONP. I planned to add FedEx and UPS too. Then we can put it on http://sipy.pagodabox.com I hope somebody can help on FedEx and UPS.
