If you paid with a valid credit card last year, and it is still valid, you can just email me and let me know to use it again. If you are in the US, please also indicate whether you want 1st class ( $38 ) or bulk mail ( $26 ) membership this year.
If you want to pay with credit card, it must be Master Card or Visa only. You can email me with the name on the card, number on the card, and the expiry date. Please include your address if it has changed.
Hope this helps, and as always; don't be afraid to email if you have any questions.
