I believe I paid retail for my set, got it from Digital Toys back in 2007 when it first came out, I was totally comitted to having a complete Classics collection, and when the thing wasn't available in Canada I went the online route.
BBTS also netted me the second wave of Legends and CD.
In fact, aside from them and Grimlock all my Classics purchases were at retail at the time of release, and since I ordered Grimlock from TRU.ca technically I got him for retail pricing as well.
I personally am surprised that a re-release hasn't occured yet, it's relatively simple to slap a similar deco on those two molds and re-release them as UM and Skywarp... Although personally I'm hoping that if Hasbro does re-issue the characters they at least give Skywarp a better purple deco for him. Classics Skywarp has a bit of an issue with his choice in decos.
