I use them all except Aldi and Lidl. Ours is small,untidy and veg and fruit goes off to quick for me.Also I don't buy bread,biscuits cakes or tin stuff so I don't need to find where the cheapest of these are.
I use Musclefood for my meat and the others for the rest of my shopping.
I look to see what offers are on and what I need that week to which one I get home delivery from. I try and stock up with toilet roll,kitchen roll etc once a month.
I pop over to Morrisons or Sainsburys if I need something during the week.But it's not very often I have to do that.
Today I have to go over to Sainsburys as their burgers today and tomorrow are half price.
