As the supplying business the onus is on Sideshow to:
1) Make quality products people want;
2) Price them reasonably;
3) Keep Edition Sizes in check so as not to over-saturate the demand
If they did that consistently, I guarantee you the NRD would never have been necessary. Now it's the customers and collectors who are literally having to pay for Sideshow sometimes over-producing stuff, missing the mark on quality, or offering items no one really wants. And for making stuff in polystone (like 1:6 environments) that could be made much more affordably from other materials while looking just as nice (this is where they fail on pricing half the time).
This Cobra Commander PF almost surely failed at #3 above.
Well, I feel far more often than not SS does all three of those.
Ah if people could show restraint and not order everything under the sun it wouldn't be needed either. Sideshow used to announce the ES on everything and it was reasonable. Then fans _____ED to high heaven that they didn't get a chance. So Sideshow did what was good for them but also what fans had asked and went to TDB. People then went crazy and ordered things cause they could. Therefore driving up ES cause Sideshow tried to do right by both. In the end collectors are fickle the love something at order time and cancel when they realize they have to pay for it. That leaves the rest of us holding the bag so I'm ok with the NRD and if it makes things better for me then great.
