Hive account@rogerwilson,
You sent 1.685 ETH so I would expect you receive:

1.685 / 0.0005 (the sale price in ETH per token) = 3,370
10% Bonus presale of 3,370 x 0.10 = 337

TOTAL tokens = 3,707

So it looks correct to me. I think you are making the mistake of looking at everything in USD$. PLR was sold in terms of ETH not USD.

I hope this helps you.
