hey dude. It's funny because i actually want one of those pretty bad myself.
I saw them very briefly in the air canada centre store (Real sports) for maybe a coupe of weeks. After that they were sold out and were never re-stocked. I went to a bunch of the downstown sports stores recently looking for the same jersey. No one had it including the adidas store which tends to carry a lot of Raptors
Seems like you and i will have to wait till the start of next season when maybe they'll re-issue some of those retro strips.
