[Baltan II]

I assume this promotion is like some of the others Bandai has had for Figuarts with freebies that aren't pack-ins. Namely, the freebies are intended to be distributed a certain way (AmiAmi's way blows the reveal that Blade's likely getting a May preorder) but stores don't have to do it. This is how HLJ tossed Decade card stands in with any random Kamen Rider thing ordered in a certain period instead of just Figuarts like the other stores.

In this case, AmiAmi is reducing the risk of ordering a bunch of potential poor sellers like Flame Dragon or Machine Winger, obvious clearance fodder otherwise, by pairing every single free stand with them. It doesn't matter if almost nobody orders some of the reissues because now they can make more money off the sales of newer, more expensive figures and force the people that need a complete Heisei Rider with anniversary stand to buy BOTH. Under-ordering the reissues isn't going to be a big deal.

It's still a gamble, but a calculated one. It would be optimal to the plan if AmiAmi did let people order multiples, but I think the usual order limits to Figuarts bites them in the ass there, forcing them to instill limits or a select few will hoard everything.
