Kind of on the opposite side of the "pegwarmers" thread, is there anything in particular from either the Legacy or Clone Wars lines that have been tough (or impossible) to find at retail near you? Most everything seems fairly easy to find, but some things have been tougher:
Never Seen at Retail
Legacy Wave 2 SaeSee Tiin
Legacy Evolutions Wave 2 (Rebel Pilots II and Imperial Pilots)
Legacy Comic Packs (Asaaj/Tol Skorr, Anakin/Durge)
Seen Once or Twice, but Not Often
Legacy Wave 1 - Leektar and Nippet
Legacy Wave 2 - Clones (Scuba and Quad Gunner)
Clone Wars Wave 1 - Yoda, Rex, and General Grievous
Legacy Vehicles - V-19
Legacy Battle Packs - Hoth Speeder Bike Patrol
Clone Wars Target Exclusive Commander Fox
Overall, things seem to have sold pretty well around here though. Really, a lot of Legacy Wave 1 and 2 can be tough to find from time to time. You can find them, but they certainly aren't plentiful. The Clone Wars stuff seems to be selling pretty well too, with the Clones, Battle Droids, and R2 being the most plentiful it seems. The V-19 is virtually impossible to find, and the Evolution sets have been pretty much sold out as well (even the glut of Fett/Padme ones at Target were down to four sets total). Even the bigger vehicles, while they can be found, do sell through from time to time to an empty shelf.
