Hello @Matt_Shipper
We tried PluginHive’s MCSA and it seemed to work great, but we weren’t crazy about it the fact tat it took us out of the Shopify order admin page (to their own page), then we did some testing of rates and our SurePost rates were higher than the USPS rates we’re currently using, so we decided to not move forward with SurePost.
Hope that helps,
Jeff
