whatever beats you may wish to purchase a lease for will appear in your “View Cart”, you pay using PayPal. And the amount you pay will be according to the type of lease you want to purchase, by checking the box for the type of lease. I believe there are 4 options, also there is the option of adding a track separation for better mixing.
You can either purchase right away or click “keep shopping” to add more leases to your cart. At the end of it, you continue you to checkout in which you will provide your billing information and then you can decide to pay with credit card or paypal
