GearXS via eBay offers this 4-Piece 300-Thread Count 100% Cotton Sateen Sheet Set in nine colors (Baby Blue pictured) for $19.99 with free shipping. That's tied with last week's mention and $14 under the lowest total price we could find for a comparable set elsewhere. It's available in full, queen, and king sizes, although not in all size/color combinations. Each 300-thread-count set includes two pillowcases, a flat sheet, and fitted sheet with deep corner pockets.
