Here is why this move would benefit the McFarlane Toys company:

1. You would get more money. This one is the most obvious point, but it's not like your benefitting from these sets only being available in the multi-hundred dollar range, so why not re-release these sets for some more of that $$$?
2. It's a pretty pro-consumer move. This would be great PR. I mean, you could be seen as a company who cares not just about profit, but getting cool collectibles into the hands of consumers.
3. This one sorta goes along with the first point but, you've even said yourself that Five Nights At Freddy's sets are your best selling series, so you might as well take advantage of that
4. Have you seen the price of the original rerun of the show stage? Are you TRYING to make these sets cost 10x-20x their original price? You can even mark all the boxes as reruns or something, I just wanna be able to get the FNAF one sets, and I'm sure many people feel the same about the other series of sets.
5. The FNAF one re-runs were very successful from what I can tell. They're almost as expensive as original sets, which means they had to have at least been fairly successful if they're as highly priced as they are.

Okay so in all seriousness, I don't actually think they will see this/care, even if this does get a good number of signatures. I just wanted to voice my feelings on this, and see if others in the Five Nights At Freddy's fandom agree. I just think these sets are some really cool pieces of Five Nights At Freddy's merchandise, and it just sucks that most of the fandom won't ever get any of them because unless you knew about these while they were on sale, you'd have to pay crazy amounts of money for these sets, and I just think it's a shame. All I want, is a rerun of preferably all of the sets, but I guess if you're only able to do certain ones then I understand.

I guess here's a hashtag if ya'll want one: #BringBackFnafSets
