Query: Never a problem with this ink

Sure, it could be cheaper. But it hasn't ever clogged and always works as you expect. I've been using my Canon inkjet printer and Canon's ink for several years without problems. I do use it very lightly (Christmas and birthday cards, and the rare time when my laser printer isn't working), so I can't attest to heavy usage. But that might be telling in itself: this ink doesn't have problems when it sits unused in the printer for months.
