Hi Lee.
Your first attempt had two in the basket. This broke the rule associated with the voucher code, so it was invalidated.
I do have an order from you for one, but you have paid for it. I have a cleared credit card transaction for £124.9 + VAT.
However, since I am a lovely person, and I don't think you intended to have two in the basket, I disabled the discount voucher after 7 sales, and reserved the last one for you. So tomorrow we will refund your credit card, and we will still send you 1 FOC iT500.
Make him pay, in fact charge him for two the greedy bugger and include a restocking charge!
