I have a nopCommerce website which uses your stamps connector.
I'm facing some issues with your plugin.
First off, i can't see the real cost for shipping, second off i can't see the proper weight for orders.
Everything is fine in order details, but let's say a shipping cost $8.92 a printed label shows $6.33, there's something wrong with those labels.

I don't really know if these problems are bugs or i am missing something in configuration panel
Thanks for your time.
