Not more than that at a time. Intentionally so on Primal's part, since they had to do such a high markup to appease Apple.
I don’t think you can buy more than $4.99.

It’s like the option is there to stay in the App Store but let us make it so limited that people will look for other means.
They wanted to have the ability for users to buy sats directly within the app, for sure. That makes it easier for folks who have never had any experience with Bitcoin to very easily see the magic of sending and receiving zaps instantly.
But yes, they keep it a small amount because they are required to have such a high markup in order for their app to be approved in the app stores and they don't want to be your primary means of stacking.
