Beer Deposit Charge?

[BomberFan73]

Hey Guys, my wife just picked up a 24 of Coors Light that is on sale...took in a few dozen empties too...
But she got a receipt and said they charged her $2.40 for "deposit".

I've never asked for a receipt before, so not sure how long that has been going on?  I think the LC has done that for a long time, but beer stores too?

Are they charging me to bring my empties back?  Seems stupid.
