Hi mmvvaa, thanks for letting me know. That sucks, I'm really sorry. It's fixed now and should be working well again! Shiphawk is one of our competitors but we're focussing on international shipping, meaning that our UPS lies in a database of lots and lots of international shipping providers.
Thanks again for giving it a try. If you happen to know any startup that sends a lot of stuff internationally, please do let me know :)
