Walmart offers the Ozark Trail 50F Warm Weather Rectangular Sleeping Bag in Yellow/Gray, model no. TKS-SBHR01, for $28.64. Opt for in-store pickup to dodge the $5.97 shipping charge. That's the lowest price we could find by $16, although we saw it for $5 less last November. It features a built-in pillow and compression carrying sack.
