You might dont understand what donations are.
A donation is a gift given by physical or legal persons, typically for charitable purposes and/or to benefit a cause. A donation may take various forms, including cash offering, services, new or used goods including clothing, toys, food, and vehicles. It also may consist of emergency, relief or humanitarian aid items, development aid support, and can also relate to medical care needs as i.e. blood or organs for transplant. Charitable gifts of goods or services are also called gifts in kind.
Purchasing refers to a business or organization attempting to acquire goods or services to accomplish its goals. Alhough there are several organizations that attempt to set standards in the purchasing process, processes can vary greatly between organizations. Typically the word “purchasing” is not used interchangeably with the word “procurement”, since procurement typically includes expediting, supplier quality, and transportation and logistics (T&L) in addition to purchasing.
Thanks for your heads up.
