I was in Buffalo today and KB Toys in the Prime Outlet had everything except the F-18, for cheap (sorta, when you consider the currency conversion). Three packs were 4.99, mini-vehicles sets such as the horses, camels, assault quad were 3.97, Black hawk for 19.99, Patrol boat, howitzer, and tank were around 14-17.99, and the watch tower was 8.97.
OT: While I was there in Buffalo, I finally picked up myself a Thunderwing with the bonus Ace. Oh yeah (Kool-Aid voice).
