I don't know if Fry's still segreates the Apple software from the PC software, but I bought a copy of Poser at Fry's years ago. I wondered around the PC software isle for about 20 minutes looking for it. I even asked a clerk who confirmed they had copies somewhere. Then, by accident, found the Apple software section. Turned out the copies were in there as Poser can run on either PC or Apple. So if you have trouble finding it in the PC isle, check the Apple one. Or vis-a-versa I guess if you're looking for a copy for the Apple.

Bought my last copy of Poser (PP2012) thru Amazon during their pre-Christmas sales. Pretty happy with their service and price.

Good luck
