I’ve big shop mentality but then when I go I only do a small shop. I think I’ve got everything I need for the rest of the year that isn’t asparagus and chicken and lettuce and a tin of something red.
One thing I miss about London is having easy access to a big supermarket. My last place there was about five minutes from one, and two others were within twenty minutes.
There’s one not too far from my flat here (still in walking distance) but I only tend to go once every two weeks or so, and just supplement with stuff from the middling sized one in the city centre.
