Dollar Tree Misadventure

What does a "Happy Birthday" banner purchased at the Dollar Tree buy you? A banner that is missing the r in Birthday.....so "Happy Bithday." FYI, don't buy birthday decorations at the dollar store. The sad thing is I hung it for Jon's birthday and didn't even catch it until he pointed it out. Technically, I should have only been charged $.93 if I were paying per letter.
