Ours is a desktop software that is currently sold from our website. But, potential customers in some developing countries might possibly find the software more expensive. Hence, we want to make it available at lower prices to customers in those countries. We are wondering what might be an easy way (i.e., not too much work) to sell the same software at different prices in different countries.
Thanks for your suggestions!
P.S. Our current selling process is the following. When the customer clicks on the "Buy Now" button on our website, the customer gets re-directed to the PayPal website. When the payment is made, the customer gets an an automated e-mail providing the download link and license key.
