What is a financial benefit given by a manufacturer to encourage the purchase of a product called?

A financial benefit given by a manufacturer to encourage the purchase of a product is commonly referred to as a rebate. A rebate is typically a partial refund provided to the buyer, with the purpose of incentivizing them to complete their purchase. This strategy not only motivates customers to choose a specific product but also enhances sales volume for the manufacturer. Rebate offers are often structured in such a way that they require the customer to submit a form or proof of purchase to receive the money back, which can create a sense of satisfaction upon receiving the rebate.

While other terms are relevant to marketing and sales strategies, they do not specifically denote the financial benefit provided to the consumer. For example, brand loyalty pertains to a customer's commitment to repurchase from a specific brand consistently; incentives can be broader and include various incentives beyond financial ones; and sales promotions encompass a wider range of marketing tactics used to boost sales, not exclusively limited to financial benefits like rebates. Therefore, "rebate" is the most precise answer to the question regarding a direct financial benefit aimed at encouraging purchases.
