Dear pop-up ad,

The internet is so riddled with grammatical errors that I rarely consider including anything from cyberspace on this blog.

However, this pop-up ad is in dire need of an apostrophe, and I doubt I've won any contest.

CDTA, Troy, NY

This apostrophe is technically used correctly, if the store was owned by a guy named Sam Walmart. Unfortunately, his name was Sam Walton, and the name of his mart was Wal-Mart. Get it? Great. Stop making it possessive....or plural. Unless you are referring to a group of them.
