Walmart offers the Suncast 31-Gallon Patio Seat in Taupe for $29.41. (Amazon has it for the same, but it won't ship for one to two months.) Choose in-store pickup to dodge the $5.99 shipping fee. That's tied with our September mention and the lowest price we could find by $25. It measures 20" x 30" x 29" and features storage inside the seat.
