Walmart offers the Ozark Trail Folding Chair in Blue or Green, model no. ZM110904Y, for $5.97. Choose in-store pickup to dodge the $5.97 shipping fee. That's the lowest price we could find by $9, although it was a buck less in August. It folds for easy storage and features a steel frame, cup holder, and carrying bag.
Note that it comes in three additional colors for about a buck more.
