When Costco used the AMEX Card I never had any issues. Now that they use the Citi Visa I have fraudulent charges on my card every few months while none of my other cards ever get fraudulent charges like my Discover Card that I use just as often online so it is obviously not a virus or keylogger on my computer. I have been asking for the service that gives you texts every time a charge is made and after a year of trying to get this I still do not have it. They always come up with an excuse of why they did not activate that feature. Costco needs to switch to another card company before they lose customers.
Bottom Line: No, I would not recommend this to a friend
