I was doing the 4-man ARC teams too Ryan. I'm up to a hefty little number of early-war ARC squads at this point too, all with red commanders. It's a nice feeling to have gotten them cheap.
I've managed now to get all but one complete set of O66 on clearance... Basically, all my extras. That ammounts to a lot more than I had planned on getting. If I see more of just about any of them for super cheap (below $5), I'm down for them... They're worth that just for the parts at that point. Some stores here had tons, some had none, some had a handful it seemed. And the %'s off varied. I found a handful (just what I needed/wanted) for 50% off the other day, got all my early-buy extras returned and replaced them with 30% off buys... Only one original set cost me full price and that was fine by me.
Did the same with my Rancor too. $40 was too much on that bad boy I'm afraid, and now I can put the cash towards my AT-TE I figure.
