Originally Apple said you couldn't charge more on the app store, but the latest version of the developer guidelines has removed that restriction, so it should be fine to charge more on the app store so that you cover your costs.
What you can't do is mention anywhere in the app that the user can buy it cheaper from your site.
You can see the exact terms in this document (you'll need to log in with your developer account to see it). The bit relating to in-app purchase is under section 11. Purchasing and currencies:
The relevant part is quoted below (note that Apple may change these guidelines at any time):
11.12 Apps offering subscriptions must do so using IAP, Apple will share the same 70/30 revenue split with developers for these purchases, as set forth in the Developer Program License Agreement.
11.13 Apps that link to external mechanisms for purchases or subscriptions to be used in the app, such as a “buy” button that goes to a web site to purchase a digital book, will be rejected
11.14 Apps can read or play approved content (specifically magazines, newspapers, books, audio, music, and video) that is subscribed to or purchased outside of the app, as long as there is no button or external link in the app to purchase the approved content. Apple will not receive any portion of the revenues for approved content that is subscribed to or purchased outside of the app
That would be kind of cheating.. Come up with schemes of combined items from your site to match apple's own..otherwise drop the idea..either you will go bankrupt or your customer will be :D (well not exactly..but you got the point)
最初苹果说你不能在应用商店收取更多费用，但最新版本的开发者指南已经取消了这一限制，因此在应用商店收取更多费用应该没问题，这样你就可以支付费用。
您不能做的是在应用程序中的任何位置提及用户可以从您的网站以更便宜的价格购买它。
您可以在本文档中查看确切的条款（您需要使用您的开发者帐户登录才能查看）。与应用内购买相关的部分位于第 11 节。购买和货币：
