I just calculated the difference between a $4.99 in-app purchase of sats on Primal Strike and a $4.99 purchase directly in the Strike app.

Primal in-app purchase would have given me 4260 sats, which works out to a spot price of about $117,136 per bitcoin.

Strike would have given me 5001 sats, which works out to a spot price of about $99,780 per bitcoin.

So you’re paying about 17% more by purchasing the sats directly in-app on Primal vs. Strike.
