You could probably sell half of your ink to either of the two people who missed out on the group buy, provided they want to pay the postage, too!
Hmmm... I suppose so, but that would leave me with less ink, not more! It's a bummer that these inks are only (readily) available in Australia - on the upside though (for me), they're dramatically cheaper than anything else I can buy, and (most of them are) very nice to play with.
To be fair, I've also got about 5 or 6 (mostly bulletproof) Noodler's inks, which are my 'staple' for work purposes where permanence is an issue; I've got Waterman Serenity Blue (who doesn't?), Visconti Brown and Diamine Red Dragon... So maybe my better half has a point?
