You can buy GuestPoints (GP) while you are finalizing an exchange for which you do not have enough GuestPoints.
The amount of GuestPoints you need will be automatically calculated and added to the payments related to the exchange.
This is how much they will cost:
- First, the GuestPoints are offered at 0,10€/GP up to a limit of 20% of the total number of GuestPoints needed for the exchange.
- Then, if supplementary GuestPoints are required, they will cost 1€/GP.
Example A: if you are interested in an exchange that costs 1000 GP and you only have 900 GP, the finalization process will automatically calculate that you need 100 GP at the price of 0,1€/GP, thus it will add a payment of 10€ to the exchange.
Example B: if you are interested in an exchange that costs 1000 GP and you have 700 GP, the finalization process will automatically calculate that you need 300 GP. The first 200 GP will be at the price of 0,1€/GP, and the remaining 100 GP will be priced at 1€/GP, adding a payment of 120€ to the exchange.
If you do not have enough GuestPoints for an exchange, you will be able to see how much the purchase of GuestPoints will cost by looking in your exchange details to the right of the conversation (you can find this detail next to "purchase GuestPoints"):
Here is a case where I posses 850 GuestPoints. I am missing 404 GuestPoints to finalize the exchange.
