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 charge. 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.

Note: In-store pickup orders won't be ready before Christmas. Shipped orders (for $5.99 or free over $35) placed by 2 pm local time on December 18 are expected to arrive in time for Christmas.
