Utility cart assembly

A utility cart assembly comprises a shopping cart, a storage unit, and at least one coupling strap. The shopping cart includes a basket and wheels positioned below the basket. The storage unit is coupled to and extends substantially entirely outside the basket. The storage unit defines a first panel positioned adjacent the basket, a second panel opposite the first panel, and a compartment defined between the first panel and the second panel. The second panel defines an opening and the compartment is accessible through the opening. The at least one coupling strap facilitates coupling of the storage unit to the basket. The storage unit is configured to customize the shopping cart for non-consumer use within a retail store. Other product, cards, assemblies and associated methods are also disclosed.
