Yes... congratz filipz.
6 months off for me still, by the looks of it, but one day maybe!
This has been my joint second best month ever. The best one was 11 sales ahead and was in March 2010. That was a month when I uploaded 10 items though, including Sketch IIRC.
The other two second best months...(yes, I seem to land on the same number every time) were both 31 day months, so I suppose of my 3 second bests, September 2011 was the best second best!
Sales do seem to be climbing slowly, but of course you can only really see what's happening if you don't upload at all for a period of time. As you upload more items, you would naturally expect your sales to grow, in actual fact, they grow slower than you'd expect, because already existent items' sales are falling off.
I suspect that the truth of the matter is that sales fall off unrelentingly over time, until they find a low level where they just tick along, selling once or twice every now and then. Look at Plamen... once undisputed #1 on Videohive....but after 6 months of not uploading, nowhere to be found in the top 20. Where are you Plamen? I guess a freelance career has taken over. Good for you!
