“It was a Christmas of smart savings and considered choices – almost every household bought into supermarkets’ premium ranges, while price remained front of mind. Discounters enjoyed their biggest-ever Christmas share, and shoppers leaned on their loyalty cards to get the best deals.”

No surprise really is it, this toxic company will gradually wilt away to nothing all the time the management bullying of colleagues persists, so many have left, good hard working people who could no longer except the rancid environment created by the chuckle brothers.
Asda does not suprise me, two weeks before xmas,prices were stable, one week before xmas they put prixes up, when l went there l brought odds, then l went to Tesco better prices, Asda also reduced their customer savings plan, my previous shop 4 weeks ago at Asda netted me 9 pence in savings, l will stick to Tesco.
Feel sorry for Asda, I use them and Sainsbury’s and Aldi.
But I find that Sainsbury’s do a deal but put prices up on other items by alot really. Asda i find compared to Aldi is there prices are cheaper than Aldi, and people don’t realise it. Aldi steak £5 where as Asda 4 £4 nice sizes thickness and length.
But since Asda was taken over, and them brothers piling all the debt onto asda, it stands at £6.1 billion i think.
They could get into serious problems.
Overall Asda,Aldi are about same, but Sainsbury’s are charging way too much really and I feel for the elderly who shop at mine.
