You can add to a completed order if your order has not yet been shipped and if you only have a few items to add. Please email info@katydidwholesale.com with your original order number and we can send you an invoice for payment./n We do ask that you place a new order if you have more than a few items to add and if the items you’re adding come to more than $50. When you place the new order, let us know in the notes section that you would like both orders to ship together. If your first order has not already been shipped, we will combine the shipping and reimburse you for any shipping overage. /n Please be advised that your order may take longer to fulfill if you are adding to the order.
