It was me that bought them. I did read the auction and I was aware that none of the jars was full, but I collect pigments and in the two years I've been seriously collecting MAC, I've only managed to get my hands on 1/4 tsp of bronze, about 1 tsp of brass and a little more than 1 tsp of copper. They're gorgeous colours and I wanted them, along with the original jars so I can transfer the other samples I have into them, for display with the rest of my pigments.
I realise this is a lot to pay for pigments, but I believe it's up to me what I do with my money and I honestly think it's pretty rude to discuss people like this, just because they don't place the same value on stuff as someone else does.
Besides, what you are not taking into account is that I am in the UK and the auction is in US dollars, so the exchange rate is on my side at the moment.
$173.73 is more than 9 full size pigments to you guys, to me it's around 6. It's still a lot to pay, but it's not quite as bad as if I was in the US and didn't have the exchange rate to help me out.
