Found it!

Third attempt and different device.

I called at Biocoop in Dol on way back from radiotherapy in St Malo. It moved some time ago but I didn’t know where to. This is old Lidl with good parking and much easier to use. Much bigger so more items for sale. Really pleased to have tracked down lavender liquid soap - these little things really matter.

Foggy, getting worse at St Malo. Very cold outside and in. Sitting with hot water bottle and blanket. Reading bits and pieces, listening to radio 4 and dozing on and off.
Gyp is snoring lightly!
