The first way to return the reusables, and our preferred method, is for you to order again! Set out your reusables on delivery day by 8:00 AM. We will scoop them up and then drop off your new order. More info on this here. If you don't plan to order again, please schedule a free pickup (located on the bottom of our Return page). If you still have a question, please reach out to us at hello@solrefill.com.
