We have been clients of WebInterpret over a year and it's been a LIKE - HATE relationship.
Their Customer Service is the worst I have ever experienced.
On the plus side - on a particularly major FUBAR, they refunded the entire amount of the customer's purchase, not just the shipping amount.
The main plus is their international shipping rates are better than we can get from UPS or FedEX, and that's why we continue using them. We are able to offer better shipping rates to Canada, AUS, UK and NZ. The frustration level and poor support make it VERY difficult to keep this service going.
If anyone has found a way to make their experience working with Webinterpret, I'd love to know how.
