This was what I found. Probably somebody with premium can find more, but yeah. :/

Also, some other things that I've found about your suggestion.

Sale #1:

As you've said, you've payed ~26 Keys on the Stormy Carribean. Therefore, 26-8= 18 Keys

Sale #2:

You've said AWP sold for P2,801.98. Since you said Keys were P110, 2,801.98/110 = ~25 Keys

Therefore, 25-5 = 20 Keys

I would say 18-23 Keys
