Paying by credit card has many advantages.
If you are not a CheckMarket customer yet, and you are ready to upgrade your account, paying by credit card means that your account will be active immediately so you can immediately launch your survey and start collecting responses.
Existing customers who pay by credit card will have their credit card details filled out automatically when purchasing extra packs of emails or respondents. You will only need to verify these details and confirm your payment.
You can update and delete your credit card details, or add a new card at any given moment.
