So, on to plan B. I would do the shopping for non perishables in person and use the nectar card, leaving the perishables to be bought online.
This, of course, initiated a discussion with Keith about what should be on the list.
"Quality Street," he said. "No," I said, "too many calories."
"Those boxes of sugary orange and lemon slices," he said, undaunted. "How old are you?" I asked scathingly, "Also too many calories and too much sugar."
"Nuts!" he exclaimed.
"Well, you can have shelled nuts," I said,
"Why not nuts in shells?"
"Because I'm not spending all my time till mid February hoovering up bits of shell which have been catapulted all over the living room," I explained. I thought that was quite reasonable, really.
Keith, however, was disgusted.
"Looks like I shall have to drag my sore feet around Sainsbury's myself to make sure I get what I want," he said.
