Milkshake brand Shaken Udder is launching its first on-pack promotion next month on more than 600,000 packs of its 330ml bottles of British milkshakes and new 200ml Kids milkshake cartons.

Each pack will be printed with a unique code which, when entered into the Shaken Udder website, will link to instant-win prizes such as milkshakes bundles, food hampers and lifestyle gifts. The top prize is £1,500 worth of vouchers from Farm Stay UK for the winner, this could mean a couple of luxury romantic weekends or a week-long stay in the great British countryside for the whole family.

“We’ve been thinking about an on-pack promotion for a while now and when we came across Farm Stay UK we thought it was the perfect fit as many of their members are farmers and all are situated in the countryside and we love supporting all things British and our roots are in farming,” said co-founder of Shaken Udder, Jodie Farran.
