From a procurement standpoint, it is legit. Most of the reviews I have seen that state it is a scam, seem to be from companies that have advertised with them. I have no experience with that side of it. But it is an excellent resource for buyers. If a company is tiny and extremely specialized, then maybe it might seem like the advertising isn't working. But I, personally, have located local and regional businesses that I never knew existed and we have established working relationships from the connection provided by Thomasnet. Com.
