The plugin is great but unfortunately, the author has abandoned this plugin and focused on other products. It is strange that someone would just leave a very popular plugin. No support at all. Sell the plugin to someone who will continue to add improvements if you don't want to.
I tried after using other pricing plugins because they looked like the best but finally I wont use it because it's not so flexible as others, just an example, you wont be able to use rows to change and easy edit columns and tables (left, right, top, bottom), you will be able to do it yes, but their process is not the faster. I will give it another try in a year.
DON'T BUY THIS CRAP. They don't even offer decent templates like before so you are stuck with ugly looking crap that is not even easy to update. A complete waste of money and time. Don't know how these people actually allow sellers like these that sell half made crap that you're supposed to upgrade to. Buy something else instead of wasting your money on this crap.
