A very good question.For that matter, after you bought the printer at a location "so wildly out of the way", why didn't you check for more convenient ink retailers?
Tell you what, Speedtoy - if you're still here, I'll help you with that one. Say which town you live in, and I'll do a couple of minutes of Googling to come up with a list of your major local ink retailers that are a lot closer than 30 miles away. Deal?
