Hello Steve:

Marketplace messages should only be shown to site admins, not those processing orders.

Is it possible for your module (or possibly a different one in the future) to include (replace) the amateuristic error messages with something more professional? The cartoonish "Oops" pages that XCart uses are quite horrible. They tell the customer NOTHING as to how to react to the errors, causing lost sales and an impression that the vendor using this software is incompetent.

This might be beyond the spec of your module, but the X-Payments pop-up error messages are also useless and could include a bit of information for how the customer should proceed.
