2-pack Ryobi ONE+ Lithium+ 4Ah batteries $59.00 @ Home Depot in store YMMV

I just picked up a 2-pack of Ryobi ONE+ Lithium+ 4Ah batteries (the good ones) from Home Depot for $59.00. This retails for $99.00: http://www.homedepot.com/p/Ryobi-…/204321540
I had to ask an associate where they were. When he came back with it, he said the price was $59.00. When he asked if I wanted another one, I said yes. They weren’t even on display. They were in a box on the shelves in an unrelated isle. YMMV
