People get very confused about prices. A community member could run a group-buy for these keys and offer them for $12 a set, bargin! But of course, there's the 'group-buy fees' and the postage and the customs if you're not in the same region, but hey, at least the keyset is $12! My price includes everything except the postage if you're outside UK. This might not be the best deal for those who are outside UK but take your complaints to Royal Mail, postage is not cheap!
Keep in mind this price is pretty standard in the UK, overclockers sell the single colour Tai Hao ABS sets for £20-something. These sets have never been done before in ISO-UK so there's that too.
Also this is being run by me, I have a pretty good reputation by now for easy and punctual group-buys. The last Tai Hao GB on GH took 2 years, my last Tai Hao GB took 2 months.
I'll re-calculate my estimates for this GB tomorrow to see if its possible to offer a lower price. I am a commercial entitiy and so obviously I'm not operating at 0 zero profit.
