run-up to Christmas as the major retailers slash prices on major brands in response to concerns over consumer spending power.
Tesco posted the biggest promotional price cut with cases of 18x27.5cl bottles
of Carlsberg Export being sold for just
£5 - a third of the regular price.
Many stores had sold out of promotional stock by the weekend after the offer was advertised in the national press under the banner of "Britain's biggest discounter".
Tesco also had 15-packs of Carling, Foster's and
Stella for £10, while the same size packs were just £8 in Morrisons in
a deal also advertised in national newspapers and on TV.
Sainsbury's was selling two 15-packs of Carlsberg banded together - a total of
30 cans for £14.99.
It also knocked
£10 off 24- can
cases of Stella Artois, at £10.99, and £6 off 18-can cases of Guinness and 20-packs of Grolsch.
Graham Page, Nielsen beer market analyst, said: "Quite clearly, as a result of the second non-summer in succession there is a fair amount of stock floating around in the marketplace.
"Take-home sales are holding up but there are still some very competitive price points.
"We could be looking at one of the most heavily contested Christmases ever as far as pricing is concerned. I can't see any alternative.
"Every retailer knows that if they don't compete with the opposition they're going to be exposed."
Page said the growth in sales experienced by discount retailers would also be a factor in the weeks ahead.
"They're selling shedloads of unbranded products, some of which are very good," said Page.
The deals came in a week when 41 MPs signed an early day motion expressing concern that Asda was selling Skol lager at 90p for 4x44cl cans and calling on the government to "look at the pricing policy of beers in supermarkets as opposed to public houses".
The motion was tabled by Tory MP Nigel Evans.
