As a BestBus member, you will be earning 1 point per every $ spent.
As a VIP member, you will be earning 2 points per $ spent.
The redemption ratio is 8 points for every $ of the ticket you are trying to buy.
For example:
If the ticket you are trying to use your points for costs $30, you will need 240 points
If the ticket you are trying to use your points for costs $20, you will need 160 points
VIP members earn double points and therefore earn free trips twice as fast.
