Hey Lizzie.
Love your site. The article about the grocery list is right on and makes so much sense. I had my master list on our PDA until it died. I'm now back to a paper list and don't really like it.
Haven't really found anything to replace our PDA as it was about 6 years old and the electronics have passed us by in the meantime.
I can't set up my list as you suggest since we seldom go to the same store twice. All part of the joy of living on the road. We use Wal*Mart quite a bit as we know the brands there but they all have just a bit of a difference in their layout.
Anyway - you have a great site and I can't wait to read more.
