So once upon a time my parents in the states sent me, a newly minted ex-pat living in the EU, a package for my birthday. It was mostly cheap plastic kitchen things, a couple of oven mitts and stuff like that. It went to customs. Not only did I have to haul my ass out to the airport, I was charged 120Euro for a box who's entire cost couldn't have been more than 30USD (and I'm being generous). I was informed that if i refused the package, my parents would be charged the full amount.
So yes, it's easy to imagine that by the time you get the package in your hands, it costs more than 100% the products price.
That seems an expensive lesson in filling in the customs declaration. Gifts are exempt from customs duties and VAT if they're worth €45 or less, and exempt from duties but not VAT up to €150.
If you ignore a parcel or reject it, it should be returned to the sender.
