Amazon offers Prime members the Koolatron Coca-Cola Personal Mini Fridge, model no. KWC-4, for $29.99 with free shipping. (Non-members can qualify for free shipping with orders of $35 or more; otherwise, shipping adds $8.70.) That's tied with last month's mention and the lowest total price we could find today by $6. It holds up to six 12-oz. cans and features a silent thermoelectric cooling system.
