We have temporarily disabled the Amazon payment method while we analyze a problem with the checkout page using that payment method. We know many of our customers like the pay with Amazon option and we are working on getting this payment method back online. In the meantime both PayPal and pay by credit card are available online at checkout and you can, of course call us to place an order during our normal hours of operation. We do accept checks and money orders if you prefer to pay that way. An downloadable order form can be found here.
We apologize for any inconvenience this may cause.
