亚马逊API项目价格

I have an issue when my script pulls the item price, the script I have that works is

foreach($items as $item) {
    $order_rows[] = [
        $order->getAmazonOrderId(),
        $item['SellerSKU'],
        $item['QuantityOrdered'],
        $item['ItemPrice']['Amount'],
        $item['ItemTax']['Amount'],
        date('H:m', strtotime($order->getPurchaseDate())),
        date('m/d/Y', strtotime($order->getPurchaseDate())),

The Code works fine with the exception of the ItemPrice field. It is multiplying the amount by the quantity ordered and I need it to just list the individual item price. If I remove the ['Amount'] bracket the value it returns is "array" instead of a number. Anyone have any idea how to correct this?
