Walmart offers the Rubbermaid Commercial Slim Jim 23-Gallon Plastic Recycling Container in Blue for $29.97. (Amazon charges the same with free shipping.) Opt for in-store pickup to avoid the $5.99 shipping fee. That's the lowest price we could find by $20. It features four bag cinches.

Update: The price has increased at Walmart; however, Amazon still offers it for $29.97 with free shipping. It's currently on backorder.
