Across multiple categories, ASDA emerges as the lowest-priced supermarket this year when tallying a full traditional Christmas basket.

Key reasons ASDA ranks cheapest:

Lower price per kilogram on fresh turkey crowns
Consistent multi-buy deals on vegetables
One of the cheapest pigs-in-blankets ranges
Highly competitive pricing on gravy, stuffing, and frozen sides
Strong promotions on chocolates and tins throughout December

ASDA’s pricing strategy mirrors 2022–2024 trends, but with deeper promotions on core Christmas dinner items.

Surprising Runner-Up: Tesco

Tesco comes in second place overall, ahead of both Aldi and Lidl when an entire Christmas shop is compared like-for-like.

Why Tesco ranks second:

Clubcard discounts on almost all Christmas dinner components
Large vegetable bags often reduced in December
Consistent discounts on meat joints and frozen roasts
Good value on desserts (especially Christmas puddings)

Tesco’s loyalty-card-driven pricing places it closer to discounter-level costs for customers using Clubcard promotions.

Aldi and Lidl: Lowest on Snacks, Not on Full Shops

While Aldi and Lidl remain among the cheapest for party snacks, sweets, flavoured crisps, nibbles, and bakery treats, they are not the cheapest for a complete Christmas basket in 2025.

Aldi strengths

Discounted Christmas snacks
Affordable bakery items
Low-cost cheeses and dips

Lidl strengths

Very low-price Deluxe desserts
Strong value on frozen party food
Cheap fresh vegetables

Yet when combining meat + mains + sides + desserts + chocolates, their total basket costs rise above ASDA and Tesco due to higher prices on turkey, gammon, and boxed chocolate assortments.

Sainsbury’s: Mid-Range Pricing

Sainsbury’s consistently lands in the middle bracket.

Typical pricing trends

Good quality, but not the cheapest
Strong Nectar-based promotions
Higher average cost for meat and desserts
Value improves for those using Nectar Prices

M&S: Premium, But With One Exception

M&S remains the most expensive supermarket for a full Christmas basket.

However, one area is surprisingly competitive:

M&S turkey crowns are closer in price to Tesco and Sainsbury’s

Especially during final-week reductions.

Consumers still pay more for sides, desserts, and bakery items — but M&S quality generally justifies the difference for households seeking a premium option.
