Fiberstore has always been very easy to shop online and to get through the check out process. I recommend them to everyone I know because they do care about their customers and always are willing to help.
Very quick, accurate, a full line of products, and at a superior price. My choice for online ordering. Note, I have never had problems with wrong pricing or inaccurate ordered items delivered. It has never happen.
Patch cables (fiber, copper and DAC) and optics are really necessity in data center. You have to backup some for long time use. I trun to fiberstore for their low price for one year. I was once annoyed by their shipping, but they really pay much efforts improving the shipping.
