GearXS via eBay offers the Lexington Comfort 6-Piece Full Microfiber Sheet Set in 12 colors for $19.99 with free shipping. Although we saw it for $4 less a week ago, it's still $4 under the lowest total price we could find for a similar 4-piece set elsewhere. It includes one flat sheet, one fitted sheet, and four pillowcases.

It's also available in Queen for $22.99, King for $25.99, or California King for $28.99, each with free shipping.
