Please Note: In our effort to protect our customer's data, we will no longer take or store credit card data in any manner within our systems. As of April 30, 2016 we will not accept credit card payments via e-mail, fax or standard mail. Please note, when contacting via phone it is not secure to leave credit card information on voice mail. We take our customers' security seriously and believe that this approach is in the best interest to protect our customers and our company alike.
