Ok, what you gotta do, is to signup for their newsletter.
It is a deal/voucher/freebie post.http://list-manage.com/subscribe?u=5ca1e871d44833f94585b76cf&id=c91e11f4f1
and simply print the voucher.
The most important
1. There are no limits of email accounts you can sign up with
2. There is a new voucher every month coming to your inbox. (last month there was a bottle of wine; this month there is a free bottle of wine, 2 for 1 on main meals, 3 for 2 tapas, 5 off 25quid spend...and no minimum order...)
If you like their food, why not save some cash, dough, cheddar, bills or money...
