I've been ordering through Tonerpak for several years now - they're life-savers. Delivery is super fast and efficient. You always get exactly what you've ordered. And they have an easier online ordering site. I've found that the Canon ink packs always deliver clean, crisp print. Yes, they cost more than the no-name alternatives, but when I tried the others, I found the quality much poorer. You get what you pay for. I print a lot of music and I need the notes to be clear and legible. So I always use Canon ink, and the twin pack is good way to make sure I always have a spare cartridge in the cupboard. Although with Tonerpak, I know if I run out, I can get replacement ink the very next day. Brilliant service.
Excellent service, easy-to-use website, great value for money - Tonerpak does it all really well.
