I'm a little confused about the wallet myself.  "Bought" sats in the primal wallet to zap users with, but not sure where the funds to do that were withdrawn from? All that was asked from the Primal wallet was my email address for the funds? I have the sats there, but for the life of me not sure how they were bought? 

 If you buy it from Primal in IOS you pay via apple app store/apple pay. It is user friendly but not recommended for big amounts/recurring buys, because you pay the app store fee. better to just transfer your sats from another wallet to your primal one.
