This article relates to promotional codes which offer discounts on vouchers at itison.com. If you're having trouble using a voucher you've already purchased, please see My voucher code is invalid.
If you see an error message after entering your promotional code, it could be there's a small typo. Where possible, we'd recommend copying and pasting your code from our email to avoid any mistakes. If your code includes hyphens, make sure to enter them too.
It could also be that your code has already been used or has expired. In either case, we're sorry to say your code will no longer be valid.
If you've entered a valid code correctly and it's still not working, drop us a line at email@example.com quoting the code in question and we'll be happy to lend a hand.
Just so you know, we only ever issue promotional codes directly and never through any unofficial websites.
