Cut the cost of Christmas dinner: Britain's cheapest supermarket turkeys Don't go for the whole bird Bargain supermarkets like Iceland and Aldi tend not to sell whole turkeys, but shoppers can buy turkey crowns or slices of turkey breast. The crown is the top part of the bird - comprising mainly breast meat. The big advantage of choosing crowns is that they are easier to carve and quicker to cook, though some complain they dry out more readily than whole birds. Iceland sells a frozen turkey crown (2.4kg) for £14, while Aldi sells turkey steaks for £2.99 per 375g pack. But crowns don't always come cheap. Fortnum & Mason's 4-5kg free-range turkey crown - reared on a farm in Oxfordshire - costs £110 and is available for delivery from December 19. Should you wait for bargains or play safe and pre-order? Many supermarkets only start selling fresh, whole turkeys nearer Christmas, and so prices have yet to be unveiled. But with the guideline of our table below, you should have a steer as to whether you're paying a reasonable price. If holding back sounds risky - horror! they might run out - you could play safe and order ahead. This isn't the cheapest route, however. Free-range turkeys direct from the farm are the most costly. Kelly turkeys (kellyturkeys.co.uk) is home to "Britain's most awarded free-range turkey" and delivers turkeys to your home on December 23. The smallest bird weighs 4kg and can be bought for £79.92, with the biggest weighing in at 10kg - enough for 18 to 20 people - and priced at £125.15. Cashback on turkeys Cashback, which many consumers use avidly around Christmas, can apply to turkey and other groceries as much as to gifts. To benefit you need to be signed up to an account - which costs nothing - with an operator such as Quidco.com or Topcashback.co.uk. The websites give money back to users who shop in any of its participating retailers including Tesco, Asda, Ocado, Waitrose and M&S. Buying a turkey from one of these supermarkets through Quidco could earn up to £5 in cashback. Take a knife to the trimmings Turkey isn't the only item on the Christmas lunch table that has rocketed in price. The cost of Brussels sprouts has risen by 19pc in the last year, while white roasting potatoes are 15pc more expensive. Consumers are apparently more inclined to cut back on these sorts of extras than on the bird itself, research by Axa, the financial group, found. It said that despite the rosier economic outlook this Christmas, half of those surveyed would head to low-cost supermarkets and bargain shelves as a way of cutting down expenditure, and one in three would use coupons and vouchers. Wine was one item where many people - 29pc - said they would try to reduce their outlay. Chocolate, Christmas pudding and other trimmings were also high on the list of potential cost-cuts. But Axa's research concluded: "Very few people are happy to scrimp when it comes to the turkey - it didn't feature in the top 10 shortlist of things people are prepared to pay less for and only two in 10 people would be happy to spend less on it." Other websites, such as mysupermarket.com, compare and track the prices of thousands of groceries, allowing you to scope out the best deals.
