World class company I’m giving them five stars despite their bizarre website tactic of blocking people searching for parts. They have an incredible catalog and more importantly, they’re shipping is world class. My orders typically arrive in just 1 to 2 business days which is greatly appreciated.

To whom it may concern To whom it may concern : Will call team member Tommy Ortega is the most processional / talented / nicest person at this McMaster Carr location , he’s all over the place very Knowledgeable, respectful among other things that I Might be missing out , I’ve been coming here for over a year and not once he’s made a mistake or left any thing out from all the orders that we have placed . Thumbs 👍🏽 up and keep up the good work Tommy !!! Sincerely : A very happy customer 🙂🙂🙂🙂

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.

As far as MRO suppliers go they are the best! As far as MRO suppliers go they are the best! Pricing is usually in line with other MRO suppliers & their online catalog is easy to use & find items. They don't tell you in the catalog what brand you are getting (unless you can identify by the picture) but usually it is a trustworthy name brand. I would say Grainger & MSC are their biggest competitors. Would advise to avoid Grainger, I deal with them on a weekly basis because my company pushes us to use them - their prices are way high, sometimes double! Their website is terrible!. I don't use MSC very often but I would say they are very similar to McMaster.

Super company I've been using them since before smartphones when their website was THE place to go to search for my nuts, screws, bolts needs. Incredible detailed drawings so you knew what you were purchasing. And now via smartphone they shined again with one day delivery with regular ground price.
