I Hate Long Lines at the Grocery Store (Especially Wal-Mart)!

• Great for outdoor events

The 3-in-1 Shopping Cart's unique design incorporates a shopping cart, folding chair, and removable bag in an all-in-one solution. The lightweight cart weighs less than 10 lbs, but isn't light on function and capabilities. The sturdy frame will support up-to 250 lbs and folds down for easy transport or storage. The seat is a comfy 12" wide and 14 1/2" deep. The large 8" wheels help navigate all types of terrain.
The 3-in-1 Shopping Cart is the perfect solution for a day at the store or a walk through the park. The seat, back, and storage area are made of an easy to clean nylon material that repels water. It even includes a zippered storage area and is easy to remove and convert to a backpack! Ample storage room is available in the bag that measures 14" x 17" x 20".

Verdict:  This would be great for customers at Wal-Mart who have to wait 2 hours to get a prescription filled-- this way, there wouldn't be so much competition for the benches or the blood pressure station seat.  Also, those who have ambulation limitations would have the comfort of knowing they had a chair if they needed to sit down.  If I was building this, I would include "brakes" for the wheels and a safety to device to lock the wheels in place.
