Morrisons belatedly launches its online service. But all supermarket chains are facing greater competition in the delivery market.
Three of our biggest names have revealed how badly they fared during retailers' most critical period - the run up to Christmas.
A new food labelling system will be adopted by all supermarkets and some producers to encourage healthy eating. But should it be voluntary?
British consumers have access to "perhaps the safest food in the world" after the horse meat scandal, according to a food expert.
Barbara Gallani, from the Food and Drink Federation (FDF) told Daybreak the Government acknowledged there were "some vulnerabilities, some areas where consumers and business are exposed", which they were dealing with after the horse meat scandal.
"The changes that have been put in place are quite wide-ranging; first of all there are more announced audits in businesses. The testing regime has been reviewed, informed by risk assessments that are now based on a much broader range of data.
"What we have learned is a much better sharing of data and intelligence, to make sure we know where the risks are."
Responding to a study by Which? that highlights the "worrying decline" in local authority food checks a year on from the horsemeat scandal, the Local Government Association said the ultimate responsibility for food safety lies with manufacturers, retailers and suppliers.

Random sampling is just one tool available to councils and a reduction in testing does not mean an increased safety risk to the public.
Targeting high-risk businesses and acting on complaints is a far more effective use of their limited resources and also allows councils to free up responsible businesses from unnecessary inspections and red tape.
It is ultimately the responsibility of food manufacturers, retailers and suppliers to ensure the products they produce or sell comply fully with food law, are fit for consumption and won't risk public safety.
Food supply chains need to be examined and a network of analysts must be set up if the UK is to avoid another horse meat scandal, an influential MP has told Daybreak.
Head of the environment, food and rural affairs committee, Anne McIntosh, said the horse meat scandal had exposed security issues in Britain's food supply chain.
"If you look at the distance that some of the food was travelling that goes into these processed foods - a. It is a false economy, b. The traceability is much more difficult to secure," she said.
"I think we have to accept that retailers are under huge pressure to provide cheap food," Ms McIntosh added.
Sales of beef products fell by nearly 3% in 2013, according to the latest figures from analysts Kantar.
- The number of frozen burgers and frozen ready meals sold fell by 7.2% and 7.6% respectively.
- Pork sales also declined.
- Sales of lamb soared by 14.2%
There is a "huge variation" in food hygiene standards across the UK, according to a Which? investigation launched in the wake of the horse meat scandal.
Food testing by local authorities fell by 6.8% over the past year, the group found.
The investigation by the consumer group into 395 local authorities across the UK used Food Standards Agency data and found:
- Bexley in London was the poorest performing local authority, with five other London councils in our bottom 10 (Ealing, Enfield, Harrow, Richmond upon Thames and Southwark).
- Cherwell District Council in North Oxfordshire was rated as the best performing local authority.
- No official hygiene sampling was carried out at all by Bexley, Christchurch, Isles of Scilly, Medway, Tamworth, West Lindsey and West Yorkshire in 2012/13.
- The overall testing rate fell by 6.8% in 2013.
- Testing for labelling and presentation fell by 16.2%
Almost one third are disillusioned with their supermarket after the horse meat scandal at the beginning of last year, a poll for Daybreak has revealed.
A One Poll survey found almost one third no longer had faith in supermarkets after traces of horse DNA were found in Tesco value burgers in mid-January 2013.
More than a third now spent extra time checking the contents of their food, the poll revealed.
A further 25% had stopped buying value food products altogether.
Supermarket Morrisons posted a sharp fall in like-for-like sales over Christmas, blaming the "disappointing" performance on difficult market conditions, heavy discounting by rivals and the lack of a full online offer.
The UK's fourth largest supermarket chain said its like-for-like sales excluding fuel dropped 5.6% in the six weeks to January 5th.
Including fuel, the drop was 7.1%.
It said it now expected its full-year underlying profit performance to be towards the bottom of the range of current market expectations, which stand at £783m to £853m.
Tesco's like-for-like sales fell by 2.4% over the Christmas period, the company announced, blaming a "weaker grocery market".
Rival supermarket Sainsbury's revealed its "best Christmas ever" on Wednesday but warned on consumer spending going forward.
