FS.COM is almost always a better price than Amazon, plenty of selections than any other local store. Totally worth the shipping time and the perfect product.

Great user friendly website, tremendous selection of products, excellent prices, low cost (if any) fast shipping. Definitely my go to store. I've never been disappointed. FYI this 10GBASE-BX XFP worths the money.

By far the best feature of this site is the live chat! I have relied on this feature multiple times to discuss my specific need and I have always had am amazing experience with the help I received.
