Amazon offers Prime members the Disney Infinity 3.0 Edition: Zootopia Power Disc Pack for $1.99 with free shipping. (Non-members can spend $49 or more to qualify for free shipping; otherwise, shipping costs $4.98; Best Buy charges the same via in-store pickup.) That's $8 less than you'd pay in another local retail store. The pack includes four power discs featuring Officer Wilde and Meter Maid Judy.
