Are you aware that the 10% discount for STH on goods purchased in the shops only applied if you put he money on your E Card and used that to pay for the goods and then the 10% is credited back to the card in the same way as buying food and drink in the concourse. I wasnt and spent £179 yesterday in the shop so missed out on £18. I realized I didnt have my ST with me and mentioned it and was told this. Had I had my ST I could have put the money on in the shop and then used it to buy the goods. Apparently this has been in place sInce we have been at The AMEX.
You can still pay cash at the wsu kiosks and get the 10% put on your card
