Hello^^
So, I was wondering if advertising shops actually help a lot? I want to get my stories out there more, since one of my goal is to get featured, but it's kind of hard to do that if you don't have enough KP for constant ad calender dates. 
 

I've done the advertising calender twice (on different stories) and it helped to propel them, but I've noticed you really have to do the ad calender multiple times for the same one, in order to gain the kind of attention a story needs to get featured (not that just because you get the calender spots a lot means you'll get featured- it's also just a good way to gain readers in general) 

I'm kinda rambling- what I'm trying to ask is, are advertising shops a good thing to use as I try and regather KP? Or will it not make much of a difference?
