I think you need to print the entire email which will have your name and email address.
is this a unique voucher? this is what I got when I try to download[image missing]
Used this today. And you can use it as many times as you like up til the expiry date
"Now print or show your server this voucher to redeem your £10 off!" Seems like you can just show it on mobile.
do you have to print the voucher or can you show it on the mobile thanks
