I wouldn't like that a bit ... still doesn't make that collection complete and yellow = Shameless.
@ Steve: Yeah, the shipping costs are a problem, I see that.
OR, I have another simple but a little stupid idea: How about releasing a new 21? Technically, there hasn't been a 21 in the series (the tin's not 'spinally' numbered and even the amarays are 21.1-3 and not "just" 21) so that collector's can fit both the tin and the single releases at the 25-27 hole. Only thing we than need is ANY movie to carry a 21 on it's spine. Collection complete.
P.S.: I know all my ideas are kinda stupid. The problem is, what's done is done and the only way to resolve this situation now is being a little creative/crazy.
