I managed to get a couple on Friday by pulling off a miracle and having a CS person from the front pull a case. Its come to that because I'm just not having luck finding these on the shelves, either.
I still don't like this particular Clone sculpt. The trooper's right arm came off the first time I attempted to get him to grip his rifle correctly in both hands. (What other possible pose could I put him in, anyway?) I just can't get past how cheap the figure feels when compared to the SA Clone. Now, if there wasn't an SA Clone, and the only alternative was the #6 sculpt, I'd be much less harsh, but still torn between the two.
I'm going to stick with just one opener and have him flanked by Kmart Clones. I'll pin my hopes on an SA army builder set down the road.
