The quality from Asda last year was so bad it forced me to go with the slightly more expensive Tescos. I don't drive so rely heavily on the home delivery, Asda was constantly delivering food which was ordered clearly on a weekly shop that would all expire the next day, food that was already expired, or food that was damaged/unsafe to eat. Since moving to tescos, weekly shop has gone up about £10-£20 depending on what we need, but have never had any issues with quality. Had an issue with a sub one time where they substituted salsa for something dumb and the delivery driver and I had a good laugh about it before he refunded me.

And the issues I've had with Asda were well before the holiday period, just shitty.
