Shopping cart
A shopping cart (also called a buggy in some parts of the United States and Canada, and a trolley in the UK, South Africa and Australia), is a cart supplied by a shop, especially supermarkets, for use by customers inside the shop for transport of merchandise to the checkout counter during shopping. Customers can then also use the cart to transport their purchased goods to their cars.
In many places in the United States, customers are allowed to leave the carts in designated areas within the parking lot, and store personnel will return the carts to the storage area. In many continental European premises, however, coin- (or token-) operated locking mechanisms are provided to encourage shoppers to return the carts to the correct location after use.
Studies have shown that it's advisable for shoppers to sanitize the handles and basket areas prior to handling them or filling them with groceries due to high levels of bacteria that typically live on shopping carts.
Design
Most modern shopping carts are made of metal or a combination of metal and plastic and have been designed to nest within each other in a line to facilitate collecting and moving many at one time and also to save on storage space. The carts can come in many sizes, with larger ones able to carry a child. There are also specialized carts designed for two children, and electric mobility scooters with baskets designed for disabled customers.
