It isn’t worth it, maybe to a collector of memorabilia but not just to play him. Buy CH, save some money, 😆.
I don’t think it will effect your save. I’ve never boughten a code from eBay but I did unlock Savini on the last day before the code expired on PS4.
Best Christmas gift ever and before anyone thinks I did something naughty to get him, the post is in off topic on the Friday forum. There was a contest (with permission from Gun) by a backer who bought codes and the game for his friend group, one of them was not interested.
On the last day I got an email, the code was for the US, I tried to give it away to the runner up, a guy name Dragonfire. The seller insisted I try it, and it worked even though I’m in Canada, it wasn’t region locked and did not change my save.
