Home Depot offers the Foss Hobnail 6x8-Foot Indoor/Outdoor Area Rug in Chocolate, Granite, or Taupe from $17.39. (Choose Chocolate to see this starting price.) Opt for in-store pickup to avoid the $5 shipping fee. That's a buck under our mention from last summer and the lowest price we could find by $18. It's made of polyester and is mold-, mildew-, and stain-resistant.
