We can edit your order within 60 days of when you made your purchase, if it still needs to be processed by our distribution center. If you’d like to remove an item, we can do so and refund the purchasing price to you. If you'd like to add an item, we can add it for you and send you the invoice for the outstanding amount.
In either case, please contact us via the submission form (select “Order changes” under “let us know how we can help you") and make sure to list the items you would like added or removed, along with your order number.
