In my extension's config.xml I'm observing the sales_quote_remove_item event. I'd like to get the SKU of the item that was removed from the cart.
I've the steps mentioned in https://stackoverflow.com/questions/4255083/magento-how-to-check-if-a-product-has-already-been-removed-from-the-cart to no avail. var_dump() on the $observer object spits out too much info to be intelligible.
I have a custom extension that adds bonus products depending on certain groups. I'd like for it to continue listening on sales_quote_remove_item but to ignore any of the bonus SKUs themselves.
