I was once genuinely interested in that Big Kill. I thought long and hard about it, did a lot of research and looked at EVERY offer from every trade.

I came to the conclusion that the interest in the Max of that set is by far bigger and offers a lot higher. So most offers on the set can't be simply divided by 2.

There are no serious offers on the Big Kill anywhere near even the currently listed 8 buds. The last suggestion was accepted "because the last sold for 7". That is technically not true either. The set was sold for 14 - and that seemed like an overpay at the time - , with the Max having offers in the 10ish non-pure range at most (if memory serves right).

I decided that paying anywhere near more than a few buds, let alone 8 buds, is a very bad investment. The current owner is trying to sell the set for a solid 8 months now (this is his 3rd attempt), with no success albeit very serious ultra-rare collectors being aware of the trade.

And as to that 30 pure offer: there is absolutely no proof of that offer whatsoever. Nobody else has offered anywhere near that. So you would think that if the set was really for sale, he would've sold by now and make a 16 bud profit, +114% instead of waiting for 8 month to get another couple of buds.

His b/o was 30 for the set, and 13+12 individually at one point in the last trade (I know, makes no sense).

His reason for not having sold despite having a pure offer that meets his b/o was: the guy, who is in his friends list, is still collecting buds and he is a collector himself and still thinking about it (look at his bp, does not look like a collector to me).

Pretty much the only one on his friends list able to afford that was "his [now revealed] real life good friend" monkey who he "asks for advice all the time".

My conclusion: he does not really have any serious offers in the range suggested here. I wouldn't even have set the price to 8 in the first place. All my research showed the value of the Big Kill alone to maybe be 3-5 buds.
