Highest was over $400 from iStock, lowest was a couple of cents, also from iStock.
You mean fractions of a cent for a
connect sale, right?

Not including the - numbers and the all zero, which I don't understand, DM sorted by commission:
Connect,2018-01,11/1/2016, image ID removed",
0.00001,15%,0.00006,Creative Image,iStockphoto,Other,"Getty",US,"California"
If we're only talking Microstock, then Alamy more than a few at $200 with the old system. I did have an agency buy the rights to distribute a series of images for $350. Single Sunset on SSTK went for $84 commission, who know why or for what use? A Sunset? I'd never know on Adobe we can't see our lifetime stats. iSTock juggled the system, I can't see back before we got "Exciting News" about ESP.
Single sales are the dessert treat after the weeks and months of nothing but dried crackers and water. And I'm sure happy for those encouraging larger sales that come in, now and then.
