Of course you can change your mind :)
We ship out orders 2-3 days after receiving payment.
If you let us know about the changes to your order before it leaves the warehouse, we'll be happy to accommodate the changes at no extra charge (and subject to stock availability). If you would like to cancel your order, we will cancel your order and refund your payment. A 20% restocking fee applies.
Unfortunately, once your shipment is picked up by the courier, we can't get it back and make any more changes :(
