This is not the largest Staples. However it's the one in my hood and so it is by far the location I visit most often.
Staff is around - usually have to wait for service but always get it. Store is clean and has a decent selection of supplies. Rarely out of stock on anything I'm looking for.
Have used the Copy Centre many times. Projects are always done when they say and prices are reasonable. The self-serve copy area has increased equipment so rarely wait for machines.
During 2013 Flood, purchased about $300 worth of supplies for Siksika - doesn't hurt to ask for a discount - I was pleasantly surprised that they gave me a nice one. Now I'm not just a customer - now I'm a fan. :)
