Sins of Punctuation

Ah, those dreaded marks of punctuation. I suppose you don't have to use them correctly in your everyday life if you hate them so, but please, PLEASE, for the love of Pete, use them correctly if you are going to write something that will be seen publicly by thousands, or even millions, of people. You know?

Here are a few fun ones that I found locally:

At Macy's grocery store. (Actually, I believe that store is named "Macys," which is another punctuation blunder).

At Wal-Mart. Must the apostrophe be so abused? I know he's a cute little guy, but that doesn't mean you can stick him anywhere you please.

Smile MY on camera? And a comma might be nice...
