Prepaid cards to buy donor?

[F4T4L1TY_98]

Hey, I was wondering if i could use a prepaid mastercard to buy iron donor for 3 months, and i was wondering if there is a tax, because the cards are 25$, and if theres a tax i wont be able to use the card since the iron donor is 25$ as well, and if there were a tax, the payment would come out with at lkeast 25,01$ and i wont be able to use it, and that would be wrong

Iron donor is 10 dollars so you'll be fine on that front.

Iron donator for 3 months is $25, one month is $10.
But sorry, I don't really know if there is tax or not. I've never donated before.
