Savvy supermarket shopper: Christmas food and wine bargains Since then the company has offered a series of other luxury seasonal lines, including a three-fish roast for £5.49, reindeer leg steaks for £7.99 and red leg partridges for £5.99. The company said sales of its premium quality products had doubled since last year, so it has been increasing the number of premium lines offered. At Aldi, customers can buy four whole quail for £4.99, if they are looking for something a little different, or a four-bird roast including duck, goose, turkey and chicken wrapped in bacon for £9.99. Christmas bubbly, too, is unprecedentedly cheap as the discount supermarkets compete with high street rivals. Lidl is offering its Comte de Brismand champagne at £9.99, reduced from £12.99 for the Christmas season. This is significantly cheaper than Tesco's premier cru champagne at £14.99 a bottle, or Waitrose's Bredon Cuvee Jean Louis Brut (£14.99). If you are not bothered by a "champagne" label, Morrisons is selling its cava, which is usually £7.49, for £4.99. The supermarket's best prosecco is on offer for £6.66 (usually £9.99). As well as Christmas purchases, customers who are looking for party food to see in the New Year will benefit from supermarket promotions in the coming week. Aldi is offering party food for £1 a pack, including 10 duck spring rolls or 12 filo prawns. These items go on sale on December 27, in time to see in the New Year. Sainsbury's Taste the Difference chilled party food lines, such as mini beef Wellingtons and prawn noodle skewers, which are normally £4 each, will be £7 for two packs until the New Year. Tesco party food is also reduced. Customers wanting its Finest range can buy three boxes for £9 across all lines, while the core party range is four for £8. A party box containing 30 pieces of food is £5, or you can buy two for £8. Other Tesco party offers include a Finest Italian meat platter at £4, reduced from £8. Finest ham on the bone is better than half price - it was £18, then £9, and is now £6.
