We’re new to Amazon MCF and setting up sending in orders via the API, US only currently.
Mostly working out pretty well, except that PO Box orders won’t seem to work. Every time we send one in, we get an error message. These are actual PO Boxes, supplied by customers. We even did a test where a customer that received a package at their PO Box needed something else, and that PO Box was rejected too (and that one we obviously know is a valid PO Box). The error is: items not shippable (we have inventory, and this error does not appear for non-PO Box addresses of the same SKU).
Any help would be greatly appreciated. Thanks!
