Good with a few bugs

The app is good. I can find what I need. Filtering is easy and effective. McMaster has the best web based catalog that I’ve used which I do a lot for work. This app I use for personal stuff. I took a star off because the checkout screen has some bugs. Even if my ship to address is showing it asks me to enter it. I can’t. I have to go back to the home screen then back to the order page to get it to show correctly and work. Same for the credit card entry. I’m using an iPad Pro with newest iOS.

Hi Azzedine, I'm sorry you've been having issues with the checkout screen. Can you send us an email at so we can work through it with you?

Best App, Best Supplier Ever

McMaster-Carr is always there to answer your questions, even though it’s not often that you will have a question because their app and website are so neat, well organized and full of and relevant information that you may seek. As someone who is often looking for new ways to do things and finding new materials to work with, McMaster’s descriptions make that a breeze. Any item you view will almost always be described as though you are learning about it for the first time making it very simple to find what you’re looking for, when you don’t know what you’re looking for is called or looks like! Shipping is also very reasonable and once you have a feel for their rates you will not second guess how much they are going to charge.

Thank you McMaster for great service over the years!

This app is great!

I'm so glad I found this app and thank you for making it. Now I can add items to my cart when I think of them instead of having to remember to do it the next time I'm at a computer. My only request is to add an option similar to your websites "is this page helpful?" link. I have a question about a product and I would like to be able to ask it without venturing too far from the product page. Perhaps you could include it on the floating link bar at the bottom?
