Yes! If you have returns from multiple orders, you can use the shipping label from your first return request to ship all the items. Please be sure you submit your return request for all items/orders being mailed back and they are being returned within the 14-day window. You can select "ship w/ any carrier" on the 2nd return and manually enter the tracking number of the return label so we know you have included multiple orders into the one box. The cost of the return shipping label will be adjusted for multiple orders using the same label.
