How do I get the original SKU of a bundle product in the cart? <p>I need to be able to get the parent ID of a bundled item during checkout to track. If a customer purchased a simple item through a grouped item, I can get the grouped SKU from $item->getOptionByCode('info_buyRequest'). Is there a way to get the bundle SKU of a purchased simple item in a similar manner? info_buyRequest doesn't seem to have this info for a bundled item.</p>
