Important Message
Difficulties placing an order? Told to "contact us"? Over the last few days we have received a few messages from people having trouble ordering via our website. We believe that this message may be tied to over-protective security 'improvements' at our merchant partner. We have contacted them to ask for them to look into it. In the meanwhile, if you are having trouble ordering, please try these things:
  • Make sure your VPN/Proxy Server is OFF.. This issue might be tied to "anonymizer" browser extensions or VPNs. Some browsers now turn these on by default. This is the most likely cause of the issue you are having.
  • Try using a different browser or device to place the order.
  • Try using a different payment method.
