If you have used paygol its not that easy to force everyone to use it, mainly since in country 1 the max limit might be 30eur, while in country 2 its 0.5eur and if you are really unlucky its 0eur.
And if you don't belive me email paygol, they will say its the curier they use and there is nothing they can do about it.
You should only use paygol for those countries zaypay dosen't work in, like egy etc.
