TLDR
buy $77 worth of eligible pens/ ink for $30 off delivered
(I have tried adding $77 worth in my cart, price lowered to $47 delivered if you have prime)
certain pens are cheaper on Amazon UK if you don't want to buy $77 worth

eg
https://www.amazon.com.au/dp/B07GF8F3Y6?ref_=plp_pc_dp_AYCI1…
is ~$5 cheaper at Amazon UK but not eligible for this offer
