I have purchased three desktop computers from Staples over the past decade or so. It's hit or miss, as to whether or not you'll get someone knowledgeable In this dept. It helps if you yourself come with some idea with what you need.
They also stock a good supply of printer ink, so if you're running low chances are they will carry it.
They also have self serve printing machines, and you can prepay a Staples card and you can scan and print away at your hearts content.
Staples will even laminate things for you that you might not like to get ruined. Like a club pass or something like that.
The one thing that I do find odd about Staples, is the grocery items. To me they really don't tie in to the whole office supply , oh let's by some Jujubes ?
in concluding my review, I think that Staples is suffering from what most retailers are suffering from. Young people today just don't want to work hard for their money. It's hard to get loyal workers for minumum wages, or just above those wages.
