Rakuten helps you save money by giving you cash back on online purchases. When you shop through Rakuten’s website or app, they earn a commission from partnered retailers and share part of that commission with you as cash back. The cash back percentage varies by retailer and can sometimes be combined with other discounts or coupon codes available on the Rakuten platform. Rakuten also offers a browser extension that automatically finds cash back offers, making it easy to save without extra effort.
