So I am looking through my pile of returns grabbing a few of what should be the easiest just to get some knocked off for the day.  Two in a row have notes about installing air conditioning systems.  One has a note saying if it qualifies for a credit, let them know and they will get the documentation to me.  Not a bit of information to go along with the statement.  The very next file I pick up has a note that they bought an air conditioning unit for X number of dollars along with a credit card statement but nothing else.  But on a positive note they did include a pamphlet on how to install their docking station for their new vacuum cleaner. 😳
