There is currently no “buy it now” button on their website, so you will have to use Paypal the old-fashioned way. Check the bottom of your Takachi quote for payment information, such as the specific email address to send Paypal to (you will login to Paypal.com, click Send Money, and type in that email address). Remember to type your invoice or quote number into the Paypal comments along with your name before submitting the payment so that they know who the payment is from.
