I found 3 of the 4 today at TRU, priced at $23.99. Of course the one set missing was the one I wanted - the AT-RT repaint. I did pick up the Dropship repaint though, and it turns out another local collector stashed one for me at a different store today, so I will be heading out to pick that up shortly.
Those are the only 2 I wanted from the set, hoping I can return the one I bought earlier and then re-buy it in tandem with the at-rt set thereby qualifying for the BOGOHO promotion.
Update: I did and was able to get a mintier box for the Dropship as well. So I ended up paying about $18 each for them plus tax after the BOGOHO deal. I'm good with that. I don't think I need an opener for either of these, so back to waiting for new figures...
