We're aware of a card payment problem affecting a small number of customers at the present time, which we are working to resolve.
Using a different browser usually solves the problem or you can use a card via the Paypal button.
Payment can be made by Paypal or Credit Card / Debit Card. Our card processing merchant is handled by 'Stripe'.
We don't store any credit card details on the website.
We take protection against fraud very seriously and provide a secure (encrypted) internet connection on login / account and the checkout / payment pages.
