Walmart still offers the Spa Sensations 4" Memory Foam Mattress Toppers
in Twin or Full (pictured) for $65
, respectively. Even better, each one qualifies for free shipping
. That's tied with last week's mention and is the lowest total price we could find for a comparable name-brand 4" foam topper by at least $5. Sales tax is added where applicable. Each one features dual-layer foam construction and a washable jacquard cover.
