Coupon or no coupon (how are we supposed to know there's a coupon? I've never heard of that store) she is still commanding at least what the other guys are getting, but if they release another Han or Chewie those prices would go down a bit. There's already been another well received Leia and another for preorder and the ANH one is still getting that price bump. Once Bespin Han is announced I bet you'll see a glut of ANH Han's hit eBay, but no one's selling ANH Leia.
The other examples you pointed at are Marvel properties. There's Iron Man's selling for $7-800 and they make 50 different IMs and there's STILL demand. Marvel is in another league above SW right now and we can't compare apples to oranges for demand. The only SW one that's pretty high is DX07 and it came with 2 figures and was released at already high price point.
You can't just be like 'oh all those auctions are people overpaying, that's not her true value' when sold auctions are the true value no matter what you think.
You seem to be arguing for arguments sake but take a look at the Tarkin individual release that is now sold out and dried up everywhere. Shoretroopers and now the Death Troopers (Which are literally meat shield characters) for Marvel like comparisons of great appreciation that are not DX07 commanding Loki, Thor prices. Iron mans are $700-$800 cause the figures are $350-$400 dollars, still in line percentage wise with a figure going from $200 to $400.
Its exhaustive to see the ol' supply/demand argument on toys. Trying to make something that is a excessive disposable hobby into a formal market model is just ridiculous. Toys are the pure definition of possession utility. Most collectors cannot afford what they buy and dump things so irrationally cause they have troubles to make rent, mortgage or credit card/medical bills. This is a ultra luxury hobby and most won't sustain the spending habbits they set out to do. They head to ebay to dump used/"MIB" items which makes ebay complete trash as any type of intrinsic valuation.
I don't know if you were collecting back when the Star Wars line first came out but the big reason the original figs (Han, Chewie, Obi Wan in particular) are not going for large sums is that HT literally made two full waves (3 month wait after the first sellout wave) of those MMS series and completely over-saturated the e-tailers with them. I picked up multiples of those three for $140 each on clearance to have for diorama builds in my collection. I think I have 3 or 4 of each they were such good deals. Leia did not get nearly the release volume they did and she is still in the ballpark, again not much appreciation above the others given the relative volume.

Believe what you want with ebay. It's so tampered with fake value sales and outright fraud its ridiculous. Just because something sells for $10,000 and others are $100 are you saying it should be the average? mean? there's no logic to ebay outside of timing. A item was purchased for this amount at this time. Then there is also recency effect and its of no rhyme or reason to set anything of fact with ebay other than it was purchased for some price on some day. If someone sold an Electro figure for $1,000 in the sold lists and no other is sold on record for months, is Electro $1,000 dollars in market value? (Careful with your answer here cause your whole position will fall apart defining your market)
By all means if you want to draw up some TA on ebay market predictions knock yourself out.
I can absolutely say people are overpaying especially if I can get it from a legit re-seller for a lower price.
