You can email me at brad@mensdenmen.com or message me through my profile or by using the contact link at the bottom of the page to let me know you would like to change cards. I'll then cancel the subscription on your current card. You should receive an email from CCBill confirming that the subscription on that card has been cancelled. The next time you sign in to the site you will be taken to a page to set up your new subscription. If you were on the "First-timer" discounted subscription plan I will have your profile set so that you will still have that option to select from.
