This deal is for anyone who works for the NHS.
NHSDiscounts have always given 7% off gift vouchers from Comet/Currys/PCWorld. But you had to go on their site, order the gift voucher, wait for it to arrive in the post and then spend it.
Well the other day I was looking for the best deal for a Nexus 7 tablet and found that NHSDiscounts now offer SMS gift vouchers. So you can go on their website, buy say £200 worth of gift vouchers, you get charged 7% less and then recieve an instant SMS message which you can use to pay for your good instore!
Much bettwer than waiting for snail mail :P
Works with anything instore including existing deals. You can even send the SMS voucher to your friends/relatives as you don't need to present any NHS ID at the tills.
