Cash-and-carry is a term used to describe a type of retail business model where customers pay for their purchases in cash and take the products with them. There are several synonyms for this term, including self-serve, wholesale, discount, and warehouse. A self-serve business model allows customers to select and purchase products without assistance from sales representatives. Wholesale businesses sell products in bulk, often at lower prices than retail sales. Discount businesses offer products at reduced prices, usually due to closeout sales or low overhead costs. Warehouses are large retail spaces where customers can purchase products directly from the source. These synonyms all describe shopping experiences where customers pay for products upfront and take ownership of them at the time of purchase.
