I had to increase all ~1$ price to ~2.25$ because the PayPal payment fee per transaction and the payout fee eat everything.

For a payout of six orders bundled I requested today, one game at 2.50, two games at 1.25, one game at 1.50 and one game at 1.99 : gross revenue 8.49, owned to you 1.82, the rest is eaten by the fees.  This was not for a bundle, but for individual purchases.
