Folks, I was in HD today and saw this nice Milwaukee M12 Inflator kit with the battery and USB travel charger - BONUS. I didn't see a price, so I had to ask an assoc. to do a price check. I couldn't find a link online for this, so it must be a special value for HD In-Store only...I'm guessing. The tool only is listed for $79, so you are essentially getting the battery and USB travel charger for free. Btw, the M12 battery and charger are $59 each.
Again, I don't see a link for this anywhere, so your best bet is to go in to the store and see if your HD is carrying it. YMMV!
