I have always received great service at Lazerquick, whether I was ordering a small number of copies or a large quantity of business printing. They are a small shop, but they can handle almost any business need. It's nice to be greeted by personable staff who know what they're doing--as opposed to the much larger copy centers in town. I'm impressed with Lazerquick.
The business material I've had printed there is top quality, indistinguishable from material I've had printed anywhere else. Promotional, letterhead, envelopes, business cards, flyers--they handle it all quickly and professionally. It's worth looking for the coupons that run from time to time in the Oregonian newspaper; they can cut your cost in half when you're doing that type of printing. (It's usually a very small coupon that runs somewhere in the newspaper itself, not in a special coupon section.)
And if you want to save more money, they also have an excellent prepaid copy card. The more copies you do, the more you save, and you can use it over a long period of time. Well worth it if you're doing a fair number of black & white or color copies.
I prefer for my business dollars to stay local, and Lazerquick makes this not just possible, but also pleasant.
