"My experience with MSC, where to start.... I work in the M.R.O. for our company. I purchase spare parts. We keep these spare parts on the shelf till they're signed out to a job. This job could be a repair, or a break down. A sells rep came in one day, making a lot of promises. He wanted to manage our pipe fittings. This is how he got his foot in the door. At first he was great, he would get us anything. We spent a lot of money with him our first year. He went out of his way to get us hard to find parts. The second year he was not helpful at all. He told us his job is based off of commission. The way his commission works is, he needs to sell you more things this January, then he did January the previous year. The previous year we were ordering for our sister company as well. Since we had spent so much money, there was no way we would meet this quota, and he knew that. He even raised the prices to try and help him reach his sales goal. MSC will always raise the prices. They real you in with low prices, and slowly raise them. There is a cheaper company out there. Use Zoro. Zoro's products are half the price of MSC's. DO NOT USE MSC!"
