Product rebate reporting requirements for personal taxes

I recently starting a side gig for a product research and feedback company. The process is this: I buy a product from Amazon that the company specificies. After I purchase the product, the company sends matching purchase price funds to my PayPal account. So I am getting a 100% on all purchases I make. I use the product and provide feedback to the company. I am wondering if I need to report any of this information on my taxes? Do i need to claim the product value as income on my taxes? Do i count the money they refund me as income on my taxes?
