Here is more information from the client:
Yes, it is a $2.00 charge to ship to residential addresses, Sarah said they have always had that charge, and we pay it for every residential order. So, when our customer goes thru the check-out, the shipping shows, for example, $5.75...when we ship it, our charge is $7.75. The thing is, when we set-up a shipment on the UPS website, it automatically detects a residential address, and adds the charge without us doing anything...so it never occurred to me that it was something I needed to watch (sorry about that).
From what I gather, PowerStore's UPS connection is not recognizing a residential address and is returning a shipping charge to the customer that does not include the additional $2.00. What is the workaround for this?
