Cool, thanks. I think I'll just re-sell it then.
Yeah, I checked how much it was going for on ebay before bidding, and it was only selling for like $1-3, so I figured it wouldn't make any difference in the bundle's price. The bundle was still a good deal though, so I'm happy. I'm pretty far in Tales of Destiny, and the disc has worked perfectly so far, and the Radiata Stories disc works perfectly so far too (though I'm only about 5 hours into it).
FYI if anyone's curious, the bundle was Tales of Destiny, Radiata Stories, and three cheap ones: FFXII, this FXI expansion, and PS2 Bard's Tale for $36 with no shipping. The FFXII is also somewhat of a bust because I already have FFXII, but I think I'll re-gift that one instead.
