These are ont he high end of the spectrum for this release. Although it is by a trusted NT member, so He kind of has a "peace of mind" advantage and justification for his price. The majority of these were purchased for resale from what it seems (FNL helped out the flippers by not placing a limit on the purchase amount). With such a high amount of these in circulation, you will see the price on these fall in terms of resale value.
I haven't gotten mine in yet that I ordered, but like I said, I won't comment on quality until they're in my hands. Based on the majority of feedback on these though, the quality is horrendous and some may end up selling for $20-$30 above retail just to move them and not lose much of their investment costs.
If you see someone listing these for over $300, slap them and pray for them, because they are obviously high on something serious.
Like my man said earlier, bath salts lol
