Office Max Ad--Missing Apostrophe

Office Max Ad (February 5-12, 2012)

I was shopping for a printer, so I pulled out the Office Max Ad. I couldn't believe what I saw (more like I was very disappointed with what I didn't see in the headline). The worst part of it was that they had a printer I liked on sale, so I had to buy it there to save money.

Apostrophe Issues....Again

I think misuse of the apostrophe is might be the mistake made most often. I was a little surprised to see this one.This shirt is available from Old Navy, not the Mizzou bookstore, but still...they offer the same typo on shirts from many different schools.
