Walmart discounts the Better Homes and Gardens 12" Gel-Infused Memory Foam Mattress in a variety of sizes, with prices starting at $128, as listed below. Plus, these items receive free shipping. That's tied with our mention from two weeks ago and at least $81 under the lowest price we could find for a similar mattress elsewhere.

  • Full for $128 (low by $112)
