For non-member orders, first boxes and gift orders, you have one hour after the order is placed to add more items. After that time, payment is processed and once your order has been paid for, any products added to your cart will start a new order.
If you are a Crowd Cow member, payment is processed 24-48 hours before your next box is set to ship. You should see the pending order in your cart and can add any cuts to it directly from the site.
If you would like to add items to your order after payment has processed, but before the order has shipped, please contact our Customer Care team here.
