I've been on P5 for about a year now (non-exclusive), and I have a small portfolio of around 300 clips. Initially, I got a sale about once every 2 weeks, but in the last 5 months or so, sales have taken a big nosedive. I haven't had a sale since July.  I've sold more clips on Adobe - where I have only around 40 clips!

Somewhat reassuring that it's just not me who's experienced a downturn in sales on P5.
