As one of its daily deals, 13 Deals offers the Geared Up Front/Back Seat Rapid Charger for $9.49 with free shipping. That's tied with our expired mention from four days ago and the lowest price we could find by $19. It features two dual-port USB chargers connected with a 6-foot cable. Deal ends January 12.
June brings some big deals and sales, but you're better off postponing certain purchases.
