I see that Rivly has category commissions that are often 1-3% lower than Amazon and Walmart. Why can’t Rivly take little to no commission at all so that sellers can really increase their profits?

First, Rivly has made the decision to shoulder the burden of several expenses that normally fall on the seller such as payment processing fees, chargebacks, and refund administration. Also in addition to the high cost of operating a marketplace, our commission is what funds our very lucrative affiliate program and advertising dollars used to drive shoppers to our sellers’ listings so we can get you more sales.
