I use PayPal when I order from them, which means you don’t have to create an account if you don’t want to. And if you check out their privacy notice they do say that your financial details are only stored for long enough to process the order and they don’t store full details on the server: http://www.ralparthaeurope.co.uk/shop/privacy.html
Thanks. I tried again, and just went directly to paypal instead of through their shopping cart, and it worked just fine. Trying to go through their shopping cart it just would not take a US zip code for the postal code, neither five nor nine digit presentation.
Anyway, I am now quite happy with some orc enroute. I will be able to round out those skulk archer speedbump units.
