Your plugin website sucks. You do not have a way for people to contact you. You are required by law in the USA to provide contact information when you sell something.
I just got a renew in 7 days notice. I do not want to renew. I deleted the plugin almost 8 months ago because of the huge amount of issues with the plugin and how it interacted with my sites theme and other plugins...and how it slowed down the site.
I do not use Paypal. When I payed for the plugin, I paid as a guest. You send out a no reply email about the renewal. This sucks.
WTF is wrong with you? Don't you think that you need to provide contact information for suppport and access to terms/conditions/privacy notices and billing dispute/non-renewal issues???
Do not renew this plugin on my credit card. OR ELSE!!!!!! Karma Karma Karma Karma
