Walmart offers the Mainstays Reversible Sequin Pouf in several colors (Gold pictured) for $20. Opt for in-store pickup to dodge the $5.99 shipping fee. That's $10 off list and is the lowest price we could find. It measures 18" x 18" x 18", and can be brushed from the selected color to black.
Orders placed with standard shipping by 2 pm ET December 20 are expected to arrive in time for Christmas.
