Instructions:I know there is the RAC discount one, but if you have a Varsity card you get 5% off as well.
There is a Varsity bar in most town and cities and a card only costs £1. Once you have it register it online and then you can type in the code on the back and you get 5% off everything at Play! Might be able to use the RAC code as well for 10% off. Not sure.
You also get other discounts with the card such as dominos pizza and others. also 25% off drinks in the bar!
