Some lightweight fold-up carts include the Rockland Santorini rolling shopping cart, the Easy Rolling lightweight Collapsible shopping cart and the 2 Wheel Folding Shopping Cart with Folding Shelf, as noted by Kmart.com, Overstock.com and Walmart.com. These carts all vary in size and price, but are at least 13 inches in length.
The Rockland cart sold by Kmart.com has a folding frame and a cloth bag instead of a metal basket. The bag is not as wide as most of the metal baskets at eight inches, but this makes it much lighter in weight. This cart weighs approximately four pounds. It has two wheels, which are dual casters. A brace helps support and balance the tote when it is not being moved. The bag is polyester, which makes it very durable and has flaps to protect contents.
The Easy Rolling cart from Overstock.com comes in red, navy, royal blue and black. This cart has a tote like the Rockland, but it is wider at 11 inches. It can hold up to 68 pounds without damage. It weighs a little less than the other tote cart at 3.8 pounds. The two-wheel cart with support brace is very similar to the Rockland as well.
Walmart.com's 2 Wheel Folding Cart is a full metal basket. It has a fold-down shelf to help keep things in the bottom of the basket from getting smashed. The basket is shorter than the totes by one inch, bringing it in at 13 inches, but it is the widest at 16 inches.
