Since the price of each type of shirt is different, it is not possible to change shirt type once you place the order.
If you want to change the product, you can contact us at firstname.lastname@example.org to cancel your order within 24 hours with no extra cost. Please email us your order number (SNAP-XXXXXXXXXX) and let us know your request. After your order is cancelled, you may order your desired products.
However, no cancellation will be accepted after 24 hours of your order placement, it's because every Snaptee product is printed on-demand and we cannot re-stock the printed tee.
