What is referred to as a collection of items to be purchased?

The term that most accurately describes a collection of items to be purchased is a catalog. A catalog is a systematic listing that typically showcases a variety of products or items available for sale, often including descriptions, prices, and images, allowing customers to browse and make informed purchasing decisions.

While a list can also entail items to be purchased, it generally lacks the detailed presentation and organization that a catalog provides. An inventory refers to a complete set of items or products that a business holds at any given time, focusing more on stock than on items for sale. Lastly, an agenda is an outline of topics or activities planned for a meeting or event and does not relate to purchasing items.
