Picked up a few figures at WalMart over the weekend just for the sake of completing second Build-a-Droids.
Since I have opened 4x each of the Quad Canon Clone, Scuba Clone and Lancer Droid, I have three spare green R4's missing a leg. So I grabbed a second opener Obi-Wan to put at my desk at work and to allow me to display a third-leg-less version of the green R4.
Same thing is the case with the second wave's R7 - I've opened 3x each of the Mon Calamari and Quarren warriors so just to complete a second R7, I grabbed my second openers of Tiin and Padme - so I have now bought every figure in wave 2 at least three times. I told myself I wasn't going to buy un-necessary figures with this line, like I did with getting extra figures to fill in a second coin album with the TAC.
Unfortunately, my will power to hold out, didn't last long.
I also grabbed a second Ak-Rev so I could complete a second drum. I bought two Umpass-Stay figures so I could have a complete drum last year, so now I have two complete drums. I gave the extra leg to one of the green R4s from Wave 2.
I will say though, I definitely like this year's pack-in (droid parts) better than last year's (coins).
