You can pay through Paypal Payment System. I do not see any of your information. PayPal handles all the information. I only see what was paid and from Whom.
If you have a PayPal account, you will have an option to use those funds. I prefer you use funds from your Paypal Account because Paypal does not charge any fees. If you use the credit card option, then I must pay the credit card fee.
After selecting "Buy Now" button, type in the rental amount requested and click on "Add"...this will update the amount being paid. Then, Select the option, PayPal, or credit card.
