I got a click and collect from Sainsbury's last week and there were loads of things missing. I was that annoyed I actually went into the shop looking for something that had been on the list I really needed, and was shocked at the lack of stuff. Drove to Tesco and it was nearly as bad. I suppose they can only put out what's delivered.
Apparently each ASDA store has been sent signage to put on empty shelves apologising for the inconvenience. They might not have empty shelves now, but they are anticipating shortages.
Shelf stacker at Morrisons here.
Apart from bottled carbonated water and oddly, quite a few ready meals, we are fully stocked as we have been everyday recently.
Judging by the size of the grocery/booze delivery we had in at lunchtime I think the store might sink under the weight. :))
My delivery arrived on Tuesday and the only things missing were iceberg lettuce and Richmond meat-free sausages. I had to choose alternative milk which arrived and my 24 pack loo roll was delivered too.
