Walmart offers the Simplify Tote and Go Collapsible Utility Cart, model no. 25501, for $16.42. Opt for in-store pickup to duck the $5.99 shipping charge. That's tied with last week's mention and the lowest price we could find for such a cart by $8. It measures 15" x 13" x 14.2" and supports up to 80 lbs.
