GearXS via eBay offers the Christopher Adams Egyptian Comfort Microfiber 4-Piece Sheet Set in 12 colors for $23.99 with free shipping. That's tied with our January mention and at least a buck under the best price we could find for similar sheets elsewhere. It's available in full, queen, king, and California king. Each set includes two pillowcases, a flat sheet, and fitted sheet for up to 17" deep mattresses.
