Overall, the experience was somewhat disconcerting. The billing being done by a third party that had their page fail to load initially, followed by a confirmation fro the museum shop that my order had been received and funded, and then no notice of any sort was received, even after I emails using the web form, until I made an international phone call to try and track the order. Surprisingly enough, the complete order was received the same day as I called.
Improvements or suggestions
Improvements:
1) Use your own web page instead of a service for charging customers. This has been the standard method for many years (I used to do web store design, so...)
2) Respond to customers when they email you (and not just with "Hi we received your email. Someone else will respond to help you.")
