I'm surprised that this question hasn't already been addressed, but I've noticed that all to often, when I view a plugin's page, and they have a free vs. "PRO" version, the price is not displayed anywhere. I go through all the tabs (which is time-consuming enough), I check the FAQ, Support, etc., but nowhere is the price listed.
I don't have time to first install a plugin and then find out what kind of functionality I'm missing out on, and then finally get to the bottom line. Does anyone else notice this problem? Or am I missing something simple in regard to finding out how much a plugin costs? I'd really like to see the price right away so I can decide if it's worth it to investigate the plugin.
