Credit Card Security
We use Authorize.net for the transactions. We also do not store any credit card info in our systems. Cards are saved if the user selects that option, but the number will not be saved on our servers. Charges will appear as Martin One Source on your statements. While we welcome questions sent by email and fax, we do not recommend sending credit-card orders by email or fax, as we cannot guarantee the security of account numbers transmitted in that manner.
If visual or motor impairments make it difficult for you to use the e-commerce site, please call 1-800-345-6087, Monday–Friday, 8 a.m. to 4 p.m. Central Time. Our customer service staff will be pleased to help you find what you are looking for.
High product demand may temporarily deplete our supply. If your product is on backorder, our customer service staff will contact you regarding your order status.
