I use Tesco for my main weekly "big" shop, but pop into Iceland (round the corner from where I live, open until 2200) during the week as necessary for the odd item. Iceland also do a nice selection of hard cheese at 3 packets for £2

Unfortunately we don't have either Asda or Morrissons round here, or I'd be there like a shot There is a Lidl within a reasonable distance, but it is very much "take your chance and spend the afternoon" given the lack of trolleys and enormous queues at the check-out I gird myself up to go there once in a blue moon to stock up on tins of salmon and mackrel, plus various excellent frozen meats.

Nowhere have I found any specifically low-carb products Although I would like to congratulate Superdrug on selling Splenda at 20p cheaper than Tesco
