This is one for the art and fountain pen nerds, and those who hoard ink (like me). Van Dieman's are overstocked on a range of colours so they're taking $2.95 and $3.95 off a selected range of inks. All are 30ml bottles. Shipping is extra, but if you order more that $100 it's free express postage for domestic orders. While stocks last, order early to secure the colours you want.
Edit: they must've run out of stock quickly because the link is broken already. You'll just have to amuse yourself by looking at the rest of their range and ogling all the other colours on offer. If you sign up to their newsletter you'll find they have specials every month or two, which I find is still too often (I have waaaaayyyy too much ink…).
Does ink change the feel of the pen?
