So, just want to float a thought. I actually think the store should be fully stocked all the time. I know the forum owner wants to keep some items rare, and thats good, but that can easily be achieved by making the "rare" items super expensive.
The way things are now, hoarders just hoard in large quantities. I dont blame the hoarders. They are just taking advantage of the current system.
But the way things are, really, who gets the rare collectible is purely based on luck and chance. Those who really really want them are vocal and aggressive about collecting them, but they are a minority. A system based on chance is going to discourage people just starting out or the vast majority who are more casual about collecting these.
I think collectibles are great, basically, they were designed to encourage active posting. But a system where there is achievability and predictability of collectibles is better for encouraging active participation instead of pure luck. A fully stocked store takes care of the problem of a few users having all of one restock.
