Home Depot offers the American Standard Colony FitRight 1.6 GBF Elongated Toilet Bowl, model no. 3189.016.020, for $44.24. Pad your order over $45 to qualify for free shipping; otherwise, shipping adds $17.24. (Free in-store pickup is also available.) That's tied with last week's mention as the lowest total price we could find by $32. It features siphon action and plastic trip lever. Deal ends March 24.
Amazon charges the same, however stock is very limited.
