$500 now isn't $500 when I was 12. I'll be buying this set for my four year old as soon as there's a decent promo to go with it. And he'll use it as a play set, causing weekly rebuilds, but that's the fun.
Sure it looks the same, but I don't care, I much rather pay Lego $550 (tax) and get a fresh box, consumer protections, free minibuild, and 5% back, than pay some flipper $550 on eBay.
