MicrostockGroup

Yes, I've had 5 or 6 this month, I usually average about 2 a month. 
I've had 14 OD sales so far which gives me over 30$ extra as a large percentage of them were for 2.48$ 

I eventually read the forum post where it explained the variation in prices for members so time for a new table for my microstock guide.
