@SS:
Looking to buy just the fighters.
Well, since they are including the F6Fs with the US Expansion set, I would imagine HBG will do with them like with the Japanese Expansion Set. First they have to get the sets made and fill all the pre-orders. Then once the sets are available as a regular item on the site for a little while, they will offer individual units in groups of 5 each. I think this is great. While you can’t buy just 1 or 2 like with previous sets, when you get them in 5 piece sets, the buying discount is already included.
Normally, with single pieces, HBG has to charge around 60 - 65 cents a piece, which he will lower if you get 5-9 pieces and lower even further if you get 10+. However, the 5 piece sets are priced at $2.50 (50 cents a piece) so you are basically getting the 10+ discount already.
I believe the F4U Corsairs from the US Marines sets are already available individually.
