If you plan to come to our office to pick up your purchase in person and plan to pay with cash you must bring exact change. We do not have a cash register because we process payments electronically using credit/debit cards, paypal, and google checkout. Needless to say, our office is the address for UPS, Fedex, and DHL deliveries - not the PO Box.
Making a purchase on our website or over the phone means you agree to our policies as explained on the Terms of Use and Help pages.
