I went to TRU tonight to check out the 4.99 sale. They had ROTS figures in megabuy two packs for 8.97 each- including 2 packs like Wookie Heavy gunner and Kit fisto, Tarkin and 65 Tactical ops trooper, C3PO and Tact Ops trooper, and many others.
Might be worth trying to fill in some holes at that rate--
