aaagh! where's the embarrassed smilie when you need one?
Got to be honest and say we don't know what the issue was, before. The webshop has now been newly computer coded (to get rid of the gremlin in the works that was there before) and we've got it to work on two separate computers with multiple test purchases. And, as you've let us know - thanks for that, - you've managed to successfully complete an order using the discount code.
Thank you for your patience while we sorted this out.
