You've done exactly what Apple want you to do. They impose this totally artifical restriction on apps to make buying direct from Apple themselves much easier.
Basically anything bought through a 3rd party app, Apple consider an in-app purchase and want a 30% share of the retail price (note not 30% of the profit).
The way around it is to exit the app and make the purchase direct from the vendors website, then go back into the app for your purchase to be visible. Obviously this is a hassle for many people. So quite a few just buy the book or music or whatever direct from apple themselves to avoid this.
It's a totally anti-competitive practice, but Apple seem to get away with it by keeping very tight restrictions on their Eco-system.
