I have just had a frustrating experience with Reship.com.
I expected the system they use to manage large volumes of shipments to be accurate and fast however have learned this is not the case. I shipped my order to them and logged in to pay for reshipment to Australia. Having paid for the service I receive mail 3 days later suggesting they got the weight wrong and subsequently decided to cancel my order and refund the cost. Great I now have to wait a week for the refund and pay for them to try again. The customer service response has been "it is my problem" which is incredibly frustrating.
