Post-It note update

I knew it was too good to be true. My friend Martha Lhamon writes

Sorry to tell you that I've been shopping with post-it notes on my wallet, and then on the shopping cart, and then dropped in the trash on the way out--for years.

So I'm not the inventor of this shopping strategy (not that I really thought I was).

But now I know how Homer Simpson felt when he discovered that Thomas Edison was the inventor of the six-legged chair.
