"The second one reads "Mustang for sale: $100.000.  5% Discount if you pay with dimes".  My point is that the "Why would I want to?" part can have a lot of explanations.  But it's still up to us to choose one.  In this particular case, I would put $5.000 against my laziness to gather the dimes.  Tuff call...

Actually it would be a very simple thing to do.  You write up a check for 94999.80$ and say here's the balance : and give out 2 dimes .  Now you just have to make sure you have proof of the promotion ad and they can't do anything but give you the discount .
