If you have a fairly good sized budget, and you are a completist type of collector, then it is a very good option for you to sign up for an automatic "list" or whatever for purchase on all of them. It WOULD be nice to be guaranteed a figure every time.
The only question with that is, you still leave some of the pick-and-choose collectors out the window. this solution only addresses part of the problem.
it would also be nice if the pick-and-choosers who are still loyal to SSC, and a bit loyal to a particular line can have a chance to sign up for an item ahead of time.
MAYBE, have it set several ways IF SSC is willing to deal with it.
Have one set for the collector's club. You set up an item number, say "A10000" and call this the 'COLLECT ALL ITEMS', and charge you the full amount... only thing is, will all of them be $54.99? That locks SSC at a certain price they may be wanting to charge a little more, or, maybe, a little less. The refunding or extra charging would suck as far as a Customer Service issue.
And then, the second part to implement is still let SSC loyalistis, through the newsletter, have a chance to buy it at a leisure time instead of putting them in a small time window to buy the item(s), and then deal with the non-regulars. No, this doesn't mean that anyone who has a newsletter is automatically guaranteed one, but like i mentioned in another thread, give a choice upfront. if you say yes, you get to buy one. if no, that's that. back to fighting with the others if you change your mind.
The figures will sell, regardless, so unless they make the sizes godawfully high, they shouldn't have too much burden of having a lot in inventory.
