First, I've tried to purchase directly on www.jetbrains.com, but it rejected my license key. Then I've contacted firstname.lastname@example.org and received a link to your website where to order. I've entered all my data and one day later received a pro-forma invoice with a very old address. Later, one week ago, I've contacted three (!) times email@example.com and firstname.lastname@example.org but received just silence. Sorry, but selling this way will not increase the income for Jetbrains.
