As much as blaming is wrong, I do believe in personal responsibility as well. I do not agree with the broad brush that's being used widely around victim blaming being 100% bad. I think it is a spectrum and in this case it definitely tilts towards the buyer.
And no - pre-order from this site is not the same as PS4 pre order. There is a huge difference between a big company that has something to lose and will stand behind its product Vs a random company that goes bust after a facebook spend - that's what makes it a gamble.
