The Great Wal-Mart Mango Mystery.

Can someone maybe clear this up for me?

I was at Wal-Mart (yes, Wal-Mart, so sue me, I needed socks) and happened past their produce section and was puzzled to see this...

"Sweetened Mango?"

And what, pray tell, is a sweetened mango? Please don't tell me that Wal-Mart, in their ongoing quest to homogenize the world, is artificially sweetening their fruit!? What's next, apples with high fructose corn syrup and red #40?

Can someone clarify this mystery for me?
