Shockwave, Wreckgar and Skywarp was more spotted in Uncle Pete's stores. Wreckgar got released in Big W and Kmart as well but in limited quantities. I don't recall seeing Skywarp elsewhere other than UNcle pete's which is where I got mine. Both the purple and gray version of Shockwave was soldin Uncle Pete's and Kmart IIRC. Uncle Pete's even had them on sale really cheap (deluxe pricing) when the new TF generations were out.
