Rebate checking is a type of financial service that allows customers to receive cash back on their purchases. Rebates are typically offered by retailers or manufacturers as an incentive for customers to purchase their products. With rebate checking, customers can easily track and redeem their rebates online or through the mail. Customers simply enter the necessary information, such as product details and proof of purchase, into an online form and submit it for processing. After the rebate has been approved, customers will receive a check in the mail with the amount of money they are owed. Rebate checking is a great way for shoppers to save money on their purchases while also providing an easy way to track and manage their rebates.
