Aw, ya made me miss my palm pilot all over again
Before palm pilot, when we were overwhelmed parents of young, I made a typed, then photocopied, grocery list of the items we bought... and most importantly,
it was in the order that the items appeared in a trip through the store. It was posted on the fridge so we could check or circle things as we ran out. Made grocery shopping the fastest ever!
I have taken the time to make "Reminder" lists in my iPhone - such as one for Costco, one for the grocery store, and one for "errands". That way you can just click the buttons on or off as you get (or finish) what you've entered. Then the list is still there for the next time. Just highlight the buttons again.
The errands list can be put into the order you need to drive that day, since it can change based on what time you start and when places open or close.
I still like envelopes though.
