Pub operator Head of Steam is launching a third "Stuff the Supermarkets" campaign to counter cut-price drink promotions in supermarkets.
The next campaign will run during April, May and June across five pubs in Newcastle upon Tyne, Huddersfield and Liverpool.
It will offer a promotion to encourage customers to buy cases of bottled products to take home at a cheaper price than those on offer in supermarkets.
Products will include beers from Harviestoun, York, Thwaites and Black Sheep breweries, Kronenbourg lager, a range of Belgian lagers in the Duvel group, Tsing Tao Chinese beer, Westons ciders, and wine.
Customers will be given collector cards and will get the free stock when the required number of purchases has been made.
Tony Brookes, managing director of Head of Steam said: "The most important aspect of this campaign is that all free stock is to be stapled into a carrier bag and taken home; it is not for drinking on the pub premises. So for every drink a customer gets free from our pubs, it is one less drink they have to buy from the supermarket."
"What we want is for every pub in the country to carry out this promotion and, that way, customers would be taking so much free drink home, the supermarkets would lose significant amounts of trade - and it would be losses in products that they care about, that they make significant profit from - the quality products ranges, as opposed the cut-price lines."
He added:"It is important that CAMRA, caring MPs, pub operators and customers get behind this promotion - and make sure it spreads like wild-fire throughout the country."
