Sam's Club continues to offer its members the Serta Perfect Sleeper Woodbriar 3 Series Cushion Firm Queen Mattress Set for $398 with free shipping. (Non-members pay $39.80 extra; you may prefer to pay the $45 membership fee instead.) That's $300 off list, tied with last week's mention, and the lowest price we could find. It comes in standard (9") or low profile (5.75") foundation sizes. Deal ends February 28.
