Whenever you sell a card, your cash balance with CardJones increases. Twice a month (on the 1st and 15th) CardJones will automatically email your entire balance to you via PayPal. If you'd like, you can also specify in your account settings not to be paid out until the amount reaches a certain level.
Once you have the money via PayPal you can then have it directly deposited into a checking account through their site (www.paypal.com). Note, PayPal may charge some customers a fee for receiving this money, depending on the type of your account with them.
