Cheap Inject Refills - wish me luck

My printer has run out of grey ink. It's funny, because I don't remember printing many grey pictures. But there you are.

Like most printers, mine has a habit of waking up at odd times of the day and night, squirting a bit of ink out of the print head and then going back to sleep. Perhaps I should look for a grey puddle under the printer. 

Anyhoo, it was on to Amazon to find out how much a proper set of cartridges would cost. The amount is eye watering. At least it made me start to cry. So it was on to look for something a little more economical. As in, a whole set of six cartridges for around half the price of just a replacement grey one. They arrive tomorrow. Wish me luck.
