Mm. Especially if these are "quickdraw" releases instead of Tamashii Web Exclusives. If the former, you pretty much HAVE to buy them then and there, or lose your chance and pay more for them later.
Unless they suck. With Bandai - heck, with any Valkyrie maker - it's kind of a crap shoot. "Will it be this release's V1 Messiah? Or will it be the V2 1/60 VF-1 of this release? Will it be worth staying up all night to get one to find out? Or will its limbs fall off like the CF 171EX?! Or... or..."
OR!
