We want to "charge up" our card shuffler customers with our spectacular free battery offer! With every purchase of a card shuffler, you will receive the necessary batteries from us free of charge. Don't worry about having to go to the local store to shell out another $4-$5 on batteries just to get your shuffler to work for your big game. We will include a set of batteries with your shuffler. Each and every playing card shuffler you purchase (excluding shuffletech brand as it is AC powered) will receive working batteries right inside your package. Our 2 deck and 4 deck shufflers require (4) AA batteries while our 6 deck shuffler requires (4) C batteries.
