If it's your first donation you'll receive 150 points plus 100 bonus points for €15.00. If it's on top of a previous donation and they total €25 or more you'll get 10 points for each Euro and another 10 bonus points for each Euro.
If you reach VIP status you'll receive 10 points and 20 bonus points/Euro.
Each progression is "lifetime" ie. once a VIP, always a VIP.
PS: It's always best to donate in Euro as the bonus point amounts are calculated against the following Euro break-points: 5, 10, 15 ,20, 25 & 50.
