In the UK I use Aldi, Morrisons or Tesco, basically just due to proximity. They are all about equal distance and have their own selling points. Morrisons: cheap petrol. Tesco: rotisserie chicken 𤤠Aldi: good copy brands, especially ice cream and that knock-off Stella type brand they sell.
I have no loyalty to any one supermarket, although I would say Sainsburyâs and Waitrose are the best quality.
