These days...
Sainsburys - #1 these days, decent fresh produce (although it does run out), best fish/non meat options of the big supermarkets, Nectar points get better prices and are quite generous with personalised options (convert to Avios). Also use for my mum for online shops. A 10 minute or so walk or decent parking in the evenings when I mostly shop (less good for bike though). Easy and quick to pay esp with Smart scan
Tesco - super close, mostly use now for certain things like single serve natural yogurts or if something like cat food is on offer. Easy and quick to pay, decent carpark
Waitrose (usually Little stores)- for the free coffee and very specific things like Jacksons bread for my mum, and decent yellow sticker. They've stopped doing my two preferred ready meals of the past
Car parking a pain
Aldi - mostly for things like nuts, their fresh produce is ok, but doesn't last, not sure about their fish and cheese tends to be very short dated. Limited choice often. Chocolate is disappointing! I like their jelly and custard pots
ASDA - only if in town, definitely gone downhill (and yes, less good value now). Clearly have an issue with theft as now one way in and out and have to walk a long way round to get out if haven't bought anything! I used to use the little one not too far away, but haven't been there in ages. Used to be good for cut flowers
Coop - barely ever, although I have bought their £30 Vintage Champagne for Xmas day after looking at reviews (did have to go to two stores) 🍾
Morrisons - used to go very occasionally, but as the Sutton one is now closed having been pretty much condemned due to the carpark on top being structurally dangerous, won't go there again
Lidl, worst of the lot I usually walk round and then either walk out empty handed or with one random thing (possibly a bakery item oops). Their "fresh" produce is dreadful IME and their fish always tastes weird - off or salty, their cheese is no better/cheaper than anywhere else, much too meat heavy in terms of their ready meals/specials for a pescatarian! Long waits for self check out, severely lacking in staff
