You can pick from two-wheeled bags or four-wheeled ones. Four wheeled ones are generally fitted with swivel wheels which are easier to maneuver through tight places. But they are pricier than the two-wheeled models, which are not bad at all by the way.
Some newer bags are fitted to a trolley-styled utility cart with large caster wheels, which makes it effortless to carry even the heaviest shopping bag. The caveat is that the cart is generally not foldable and will require a separate storage space.
