Possible glitch free £5 amazon with voucher codes.
Found 20th Nov 2017
I was looking to book a hotel and stumbled across the the voucher codes website, basically book a hotel through them and you receive a £5 amazon voucher. The day I was going to check in I had to cancel as I no longer needed the hotel, So I went on the travel lodge website it was very straight forward and cancelled. 3 days later I got my refund and happy days. I just checked my emails today and the voucher has been tracked and just recieved my £5 voucher, it works and I have just bought something. Maybe this was a one off but might be worth a try.
