Why would you invest and resell on sets that you don't even want yourself. There is literally no demands for this set.

Good price but not very fun to build it. Guess the qty is pretty large in the market.

Amz has the same price now.
Not sure why people thought my option is not helpful. In fact there are many Lego resellers out there.

It's enormous since this set was suppose to retire YEARS ago and never did. Probably one of the most delayed retirement sets ever.

It has no demand because it was not retired as expected?

Yeah, I've noticed Lego has delayed retiring sets (especially popular ones) more and more lately- the Medieval Blacksmith set is another example.
I don't blame them. Make profit when you can.

This is my philosophy. I am not really a lego investor, more of your general occasional ebay seller, but I do pick-up sets when there is a really good deal. But I only buy sets I am interested in, so if I never re-sell I will have fun building it.

Not sure what you mean by no demand - this set has been a hugely popular set for years and years, and is still a best seller on Amazon. Still one of the higher ranking current sales sets to be retired if it actually retires this year.

Is this actually a good deal? Seems fun to possibly build with the kiddos at some point. Kids are 2.5 and newborn lol.
