I have had good luck with PC-Canada.com. I've ordered over 20 items from them over the past couple of years and have had good luck every time. Prices almost always beat the big box stores and shipping is fast. My PA271W-BK-SV monitors came from PC-Canada and we saved over $400 on those alone. I buy all my Epson 3880 ink from them too. Tried BestDirect.ca a couple times since their shipping was free, but they never delivered either of my orders. Totally useless, but PC-Canada has been quite good.
