Q: I just checked my email and realized my 8 year old son ordered over 90$ in app purchases! I am at a lose of words. Is there any way I can get this money back!?!? Please help me

Welcome to the Apple community.

Generally speaking Apples policy is that sales are final. I suppose you can try appealing to them. Select the content which is causing a problem and use the 'Report a problem' button in Your Purchase History.

To address this for the future, turn off In-App Purchases in the Restrictions on the iPad/iPod/iPhone he's using.

Regards.

Using the Report a Problem link Winston described, I believe there is a selection for

"I inadvertently purchased this item."

There is a way due to a lawsuit apple is giving out refunds you need to contact apple and have proof of purchase
