I remember the stamps too. My mom would collect them in order to buy things that she consider 'luxuries.'  I still have the card table and chairs that she bought with them, can't find one of the quality now!

This blog brings into mind the 'Brady Bunch' episode where both the girls and boys were saving the stamps, the store was going out of business and they had a contest to see who got all of the stamps in order to buy what they were saving for.....  

As for the two dollar bills, I've seen them but rarely.  I remember when they came out, my family had gone to Mt. Vernon, Thomas Jefferson's home.  Well they gave you back two dollar bills as your change so if you were due back 10 dollars, you got 5 two dollar bills.  When teaching money to students, the text books don't show, mention two dollar bills or the one dollar coin (and these are new math programs).

Meijers uses the finger print devices as a way for the cashiers to log onto the registers.  Noticed when I went shopping Friday, that the one had trouble logging on.  He kept wiping his hand on his pants to try to get it such that the 'reader' would recognize his finger.  Took him about four attempts before it let him on.
