eDart Shop review for UPS Shipping (Official)

I initially had some reservations about using the UPS app in Shopify, but all my concerns were promptly addressed by Ruben from UPS. His helpful email guidance (such as how to input poly mailer dimensions correctly) made all the difference in my decision to give UPS a try. In the past, I relied all my shipping on USPS. However, it seems like UPS offers slightly better rates for bulkier shipments. So I'm excited to test out UPS for my upcoming shipments!
