Hand up in the air... I do, I do! My memory was impeccable when I was younger, but now that I'm in my 50's, forget it. I have a hard time remembering from minute-to-minute, never-mind day-by-day. I usually start compiling my shopping list a few days beforehand, and what a change in shopping. No idle looking at things I don't need... no buying things I don't need... just in and out, and way faster compared to when I hee-and-haw and pause down every isle I go. So nice to be able to arrive home with all that one needs!
