I guess it all depends on how the figure comes.
If the figure comes in a smaller white mailer box only slightly bigger than the figure and the figure is in a clear baggie, then yeah, I think $6.99 is a bit much.
If the figure comes like the George Lucas Stormtrooper figure in a larger box and all carded up, then I'm okay with that. I'm sure we'll see how Captain Rex will be shipped at Toy Fair.
I'll still probably get at least three since (a) I have a mountain of the UPCs since I bought double TAC for the coins, I could sacrifice 60 bubble inserts and still have a full set - PLUS I have all of the inserts from the army builders and (b) two of the three GL figures I got came in less than mint condition so 3 gives me better odds.
