Premiere CC

I need help.

Please let me understand how to pass from a 30 day trial to buying the product.

I only found a request to adhere to an Adobe "Creative Cloud" program and do not understand if that will give me the right to doenload the program/s or if it is just a first step to deposit files.. How much does Premiere cost? can I buy it directly from my Apple iMac applications?
