I received my Commonwealth Games ticket and a voucher as well which entitles me for a £5 discount if my spend is at least £30. I wanted to buy something anyway, so selected two articles with the worth over £30, entered the code, got the discount calculated, however, when I got to the stage where I enter my credit card details, the discount was gone. I tried this twice with the same results, so gave it up (hopefully this has been fixed since then), but later returned and bought a nice t-shirt which I have received and like it a lot - a nice memorabilia! Looking forward to the Games :)
