Walmart offers the Coca-Cola Personal 6-Can Portable Mini Fridge in several colors (Black pictured) for $29.99. Opt for in-store pickup to dodge the $5.99 shipping fee. That's tied with our mention from last week and the lowest price we've seen. (It's the best deal now by $13.) It features a removable shelf, self-locking door handle, and a warming function up to 135° F.
