Bizarre customer service. Checkout procedure on website doesn't provide a shipping quote. Received an email requesting additional information for shipping. Provided information and asked how much for shipping, got a reply back from someone else saying the order is cancelled due to non payment...

McMaster-Carr is fantastic! I've been using McMaster-Carr for years. They always have the bolts and other hardware that no one else has. They also have very good pdfs with dimensions as well as CAD renderings. These are very important when your building prototypes and trying to figure out what may or may not work on a one off project. The best part is you get them either the next day or the following. Highly recommend!

Nonsense shipping policies At first they let me know I was able to receive the order in Mexico, however I decided to receive it at El Paso, because of the shipping price, without explaining them further info They let me know they can't ship my order to any address inside the U.S. since I'm probably going to take the order outside the country and they take a "conservative approach to shippments outside North America" Literally only ordering 4 locating pins... Reading the rest of the reviews I found out they really don't like foreign people, I thought it was only for the Mexico thing, but nah

Shipping Cost Surprise - Huge! I recently placed a small order - just over $20 - with McMaster-Carr. During the order process I was not able to see, or even estimate, the shipping cost. All I got on the order page was "shipping and tax will be added." OK, I figured, I'll take a chance. 24 hours later, my shipment was in the mail and I finally got a receipt showing the shipping (and tax) amount. Turns out the shipping was more than 40% of the total order, making it substantially less competitive with other suppliers. My advice: (1) shop around. (2) If you MUST buy from McMaster-Carr, don't press "buy" until you know the shipping cost.

Best source to quickly find hardware and other supplies. Freaky fast shipping too!!! I use McMaster-Carr primarily for automotive needs. Using their web site is super easy by far the best site to quickly get to what you are looking for with no fluff or "offers" to interrupt navigating your way around. Finding hardware and electrical supplies is a breeze. I highly recommend using them if you are in the SouthEast. Most everything I have ordered literally shows up the next day even though I didn't select next day shipping. They may not always have the best price but the quality of goods combined with showing up the next day wins in my book. No one at McMaster-Carr asked for this review. I just felt I needed to share with others how awesome they are to work with.
