The move - designed to generate footfall in the run up to Christmas - will also see prices slashed on the Moet & Chandon and Nicholas Feuillatte Champagne brands, which will sell at £12.99.
The promotion will launch on the 23 November and customers will be limited to three bottles per person.
The Christmas Champagne price wars are a key battle ground for retailers.
In 2007 Asda sold bottles of Dom Perignon for £30 a bottle in a bid to entice Christmas shoppers.
Marks & Spencer, Ocado and Waitrose have also moved to heavily discount their fizz - particularly to consumers who buy six bottles or more.
The move comes as figures reveal British consumers are taking the edge of the credit crunch with copious amounts of Champagne. According to Morrisons sales of champagne at the supermarket grew by 21.1% in the last three months. While according to AC Neilsen figures, 12 weeks leading up to end of October the Champagne market grew by 3.3%.
