Limited edition-wise: probably FFXV Ultimate Collector's Edition, coming up to $302 after shipping/taxes.
Kickstarter, without Backerkit add-ons: Knights & Bikes Collector's Edition at about $238
Otherwise, for things like eBay or through previous owners, I usually will purchase games for at most around $45-60 depending on the item. I remember paying $80 for both .hack 3 & 4 and feeling like maybe I paid too much at the time.
