Lego faggot here that has bought and sold lego on ebay. and that set number is legit and the kwik-e-mart set has been long retired. Retired sets do triple or more in value as time goes on. This one more so considering it's one of two large simpsons sets lego made

600 though seems what would be the current market rate for this. I believe this was 150 to 200 when it was first released.

As for the near 9k asking price you see this a lot on ebay where a person will ask for a stupid amount. You can ask all you want but what it sells for is a different story. Even in listing shown you can make an offer lower than the asking price. Sellers do this in hope of finding someone desperate willing to overpay or to make sure they don't sell below market value.

Basically there are plenty of things coming out right now that is showing progress from the audits to lawsuits etc....this seems more of a distraction to me than anything else.
