Crazy world example #1

Crazy world example #1: Staples wants $23.40 to print 40 pages in color and duplex in their Copy & Print center. They can also sell me an HP Deskjet 2512 All-in-One Printer for $39.99. So, for an extra $16.59 I can buy a printer for this one use and a few more pages afterwards and then throw it away.
