Our website now allows online shopping with credit card payment for U.S. orders. However, the final shipping & handling cost, which depends on the volume, weight, ice, and shipping distance of the package(s) will not be known at time of checkout. They will be determined at the time of shipment. Therefore, if you choose to order online, the credit card will be charged twice: once for product(s), and once for shipping & handling. If you prefer a single credit card charge for both the product and shipping & handling costs, please phone (858) 453-0848 or toll-free in the US and Canada (800) 645-0848.
