Change the price of in-app purchase item after publishing android

Is it possible to change in-app purchase item's price after it has been published in Google Play? (I'm assuming the app has been published, too).

The whole documentations online at http://developer.android.com as well as http://support.google.com/googleplay/ have nothing about it, only mentioning the possibility of changing price of an app, not the in-app item.

Does Android charge for in-app purchases?

Apps and in-app products sold through Google Play's billing system or an Additional Billing System (as defined below) in accordance with the Payments policy are subject to a service fee.

How do I remove an offer from in-app purchases?

Tap Settings. Tap In-App Purchasing. Uncheck Allow In-App Purchases.

Yes you can change prices at will.
