Credit card transactions

Are credit card transactions on safe?

Absolutely! In fact, it is statistically safer to use your credit card over the Internet than in a restaurant or department store. servers use Secure Sockets Layer (SSL), an encryption technology that works with Netscape Navigator, Microsoft Internet Explorer, and AOL’s browser, so that only can read a customer’s personal information. If you would like more information about our credit card security policy, please read Privacy and Security on bottom link on our front page. (You may have to scroll down.)

Why would my card be declined if there are sufficient funds in my account?
In order to protect our customers from fraudulent transactions, the billing and shipping address is verified through your credit card company. If the billing address on your First Endurance account differs from the billing address on your bank’s records, you could be declined. Please verify that your account information is correct, and then notify your credit card company to ensure that they have your most up-to-date information. Additionally, we do not have the capability to validate funds on cards issued by foreign banks.

Payment options

What are my payment options?

We accept Visa, Mastercard, and Discover credit cards.

Product availability

Why would an item be out of stock when it still appears on your site?

Because of some unforeseen increased demand, First Endurance may sell out of any product at any time. First Endurance will do everything within our power to always have product in our warehouse.

Sales tax

Does charge sales tax?

State laws require that internet retailers collect sales tax in states where the company has its base operation. headquarters are in Salt Lake City, Utah. Subsequently we are required to charge applicable taxes in Utah.
