I think trading should be fine.
It is just the profiteering that bums me out personally, and what kind of took the "fun" out of it for me. Though this sale got me excited since I really like some of the colors that were included. I also do not mind at all that prices have been raised. Better that it goes to the creator than the middle man, and it reduces the opportunity for profiteering. I have been pretty lucky on 4grabs and got in this time as well.
Definitely agree like most people it seems, that the price raise is good but I disagree that it reduces the opportunity for profiteering, re-sellers will just up the prices more to compensate.
If someone lists one of these 'new' clacks for sale for a large markup the best thing for people to do is just not pay it.
I am not sure how this will pan out. What I personally would expect is that market prices for clacks are not directly related to their retail price, and people's willingness to pay for them remains unaltered. In that case, there will be less to gain from re-selling clacks. Though this is just speculation and I really do not know what will happen, since the prices of "collectors items" do not seem to follow the logic of normal goods.
I agree with Spamray that in the end, it would be best if people would not buy at inflated prices. Though of course, that is impossible to control (I myself have also paid more than triple times retail for some items, though I regretted it and since then, I have decided not to take part in this kind of thing).
