I'm sure, however, they received complaints from customers receiving ziploc baggies with pills in them.
Another thing to ponder is this silly question: If product is marked down from $19.99 to $9.99, it looks like a pretty nice deal, right? What if it was only marked down from $10.99? Not as significant of a price drop. That being said, and taking into account the fundamental law of demand, I don't think you'll have to worry about them selling it for $19.99 anytime soon: they wouldn't make any money.
Lastly, Sam and Matt are two very smart fellas who know how to do business. I totally trust they know what they're doing.
