Costco offers its members the Brondell Swash CS1000 Bidet Toilet Seat in Round or Elongated for $299.99 with free shipping. (Non-members pay a $30 surcharge.) That's $50 under our October mention (which didn't require a membership) and the best price we've ever seen. (It's a current low by $300.) It features a ceramic heating system, warm air dryer, and multiple spray options. Deal ends December 12.
