Some of the most expensive liquid on the planet
It hurts. I bought an Epson R220 for £80, then found that a set of inks will cost £42 !

In case you wonder what the answer to that question is:
"Why use genuine Epson ink?Under 'Greater value' we learn:
- Superior image quality
- Longer print life
- More reliable
- Greater value"
"Individual ink cartridges make genuine Epson inks more affordable than ever."even greater value for money" - greater!!!! - like the other is already 'great value' and this is 'greater'. It's just not true.
... From just €9.99 for an individual ink cartridge, printing photos, schoolwork, letters, flyers – or whatever you want – is affordable and fun with Epson.
Offering even greater value for money, Epson inks are also available..."
When you read that 'Some oil traders are calling for $80 a barrel while more aggressive ones are setting their sights on $100' (- a barrel is 42 gallons!), you realise that oil is done. Inkjet ink is where it's at. Sink an inkjet ink well if you want to make it big.
