OK, anime fans, hoping somebody that keeps up with anime news can answer this querstion for me.

I was buying Funimation's One Piece DVDs off of Amazon at a pretty good discount off of MSRP and missed Season 2 Voyage 5. Shortly after I got my last DVD order in, I went back to get this last disc I was missing. Only it suddenly shot up to $180 on Amazon and I can't find it anywhere else (I have a backorder in with Best Buy, but I don't have high hopes for it working out).

The weird part is that every single other disc Funimation has released so far, up to season three fifth voyage is still available everywhere for well under MSRP. It is this one single volume that for some reason has all but completely disappeared. Was it a really good set of episodes or massively underproduced or what?

And yes, I know, Funimation is doing much cheaper collected sets now, which I'll buy starting with S3, but it irks the hell out of me that I've got to re-buy 6/7 of S2.
