Reputation Olive Green Jacket Price?

Hey guys! I've been wanting to purchase a Reputation army jacket for a while now, and have just noticed a couple popping up on sale sites recently with a pretty large price range! I think if I don't buy any/much showgirl merch, I'll spend money on this instead and was just wondering, what do you guys think is a fair price to pay? If any swifties have sold or bought one resale, how much did you sell or pay for? They're obviously quite sought after, but obviously there is a limit on how much I can pay and how much is fair, so I wanted to come on here and ask for everyone's opinion! Thanks so much in advance for your advice!
