Literally a used Switch game in a big, ridiculous bag with a “New” sticker on it. Imagine going into a GameStop with a game in a bag like this and convincing them to give you credit for it as “New”.
Don’t buy online from GameStop. Actually, just don’t buy from GameStop.
I'd demand they honor the 75% off sticker on the assumption that they removed the original shrink wrap to place it on the cover.
