We always get paper from Staples and buy Ink cartridges for two printers and find that Staples is the closest most conveniently for our needs. We have purchased all kinds of supplies from Staples and find it the easiest to deal with.
I ordered a case of paper because it had a rebate on it. When the case arrived it appeared to have been opened and re-closed - there was scotch tape holding the lid on. When I opened the case I could not find the shipping documents and I found that several of the reams of paper had burst open. The paper was stacked in such a way that some of the edges were bent - making them unusable in my printer. However I did use them for my grandchildren to draw on when they come for a visit. I filed the rebate on-line but have not yet received the card. I am looking forward to that arriving soon. I have bought from Staples for years and have never had a problem. Needless to say - I was surprised and somewhat disappointed.
