I had some concerns about the security of the online ordering system as although the form is submitted on a secure connection (https) it is then emailed to Silverprint. I spoke to them on the phone and they informed me that several people had queried this but and that, yes, the form is emailed but only between internal servers in the same hosting environment and so nothing is sent insecurely on the internet. It's a shame the website functionality is so poor. I think a proper e-commerce site would be great. It is a real trial placing an order in the current system.
Great service though!
