But you're basically questioning the obvious... for a pattern the natives have seen for almost 10 years now. This is why your question isn't getting any love.
Like all markets.. when the flipping gets good, the more people try to get in on the action. This has been going on since games like Star Trek and Metallica fueled the 'get on the list' FOMO.. and since then Stern and others have been milking the 'limited availability' aspect of things. The flood of new money willing to pay thousands over retail for something creates this perfect storm where the opportunity is too great and everyone and their uncle tries to become flippers of games, accessories, etc. You see it moving into Mods now too as they too try to cash in on the 'limited availability' fad to raise prices 200%.
Your thread isn't getting any love because it's all crap we all already know and no one likes. But it's going to keep happening as long as the new money in the hobby keeps flowing like it has.
