These are fees charged depending on the processor to help cover the costs they charge us for their service. These fees do not even cover 50% of what they are charging us, but it does help make things a little easier to bear. (Honestly).
Do note that these fees change from time to time. For a time, we had a 3% discount on Mastercard transactions.
These things change as our deals with the processor's change and our need to direct dollar volume to certain methods to satisfy the bank's change fluidly as well.
We will always keep these fees as low as possible and seek to negotiate better terms with our processing partners in order to pass the savings onto you, the customer.
It is truly our goal to get modafinil sent out to everyone in the world who needs it, trumping greed. This is my word to you.
