Sounds like this sign could have been taken either way. I wouldn't consider it false advertising though - that would be the case if they clearly stated Pants and Sweatshirt both for $19.99. In this case they were simply stating Pants and Sweatshirt $19.99. It never said BOTH for that. They were simply stating the price was the same for each. There are always people who twist things to try to get a deal. I'm sure if it wasn't that, it would have been something else.
