The folks at Ink Toner Store are very polite. It's clear customer service is important to them. Their site is easy to navigate; and when looking for toner with multiple types of printers, a simple site helps customers A LOT. The ink comes very professionally packaged. And works great in the HP laser printer. Coupons online are a big plus, too! The two things that would get a 5th star are: 1) have an installation or instructions sheet in the box, (for those of us who don't change toner every day) 2) make efforts to partner with groups that can recycle your products.
