Abacus One vs. The Others

Sure, you can run to your nearest office supply store and purchase your printer and data supplies, but they don’t care how many trips or the number of phone calls you make before you have everything that you need to be successful.  In fact, every call and every trip you make is an opportunity for the chain stores to sell you something you didn’t intend to purchase.  At Abacus One we value your time and appreciate that the less time you spend shopping for supplies, the more time you have to produce.  Think of us as your Personal Shopper of the printer supply and data media world.  When you purchase your supplies through Abacus One you are receiving personalized and efficient service as well as quality products.  We won’t try to sell you pencils when what you need is toner

The reputation of Abacus One rests with it’s owner, Judy Gatena, and not only does she believe that her customers are more than their order, but at Abacus One her word is her business!
