Costco offers its members the Bio Bidet USPA 6800 Toilet Seat in Elongated or Round for $249.99 with free shipping. (Non-members pay a $12.49 surcharge.) That's the lowest price we could find by $230, although we saw it for $50 less last December. It features multiple wash functions, tank heating system, dual nozzle, adjustable heated seat, intelligent body sensor, and remote control. Deal ends November 19.
