I had a $112 sale on Friday from what appears to be Brazil. I just got another $112 sale from same location. Coincidence or trouble?

Sounds a bit too much of a coincidence to me.  I'd query it I were in your shoes.

Could just be the same person buying several images for the same use, so same fee.
Congrats!

That was remiss of me.

Indeed!  Congratulations if it's all above board.

(Sorry to be so negative - put it down to the fact that I don't tend to have good luck at that level of frequency!) 

Nor I. This sort of thing happened about 4 years ago even though SS paid many of us for a bunch of illegal purchases. If its on the up and up I'll be very happy. If not, we're having astounding sales.

Have a look at the images which were sold. If they are not the same, I would say drinks are on you

Definitely not the same...
