For in-store pickup only, GameStop offers the Disney Infinity Power Disc Capsule

. (You'll have to complete a form for a "hold request".) That's $2 under our April mention and the lowest price we've seen. (It's also a current low by a buck.) It holds up to 22 power discs and features a slide-tray, and hexagon and circle Dual Power Discs bands.
