It's not much cheaper (especially considering the 10 euro postage within Europe), but you try contacting the seller(s) to try and get them for a lower price, or inform if there's a sprue of which the bag has been opened or a part broken off the sprue (but inside the bag). Modellbau Seidel doesn't seem like a store to me where they'd ship those bags to customers unless they are aware of the 'imperfections' and have accepted them
It's how I got a 10% discount on my TRF201 (creased box) elsewhere
(whereas there were none listed in stock).
