From my own personal experience, that's the smartest thing on Newark's site.
Last week I went to Newark's site to order some parts and logged in with my account, which I've had for several years. I found my parts (not always an easy task on their site), placed my order, confirmed my billing address, shipping address, credit card, shipping method and clicked on "Submit Order."
I waited and waited and waited and waited and...
Their site kicked me back to the start, clearing my cart and all my information in the process and forcing me to start over. All the page said was, "There is an error in your submitted information, please resubmit the flagged items."
Everything was flagged.
After several more tries, all ending in failure, the site finally tossed out a message that I needed to contact Customer Service at their toll-free number to complete my order. Which did me no good as the number simply went to a recording telling me that they were closed and to call back during business hours.
After fuming a bit and discussing my frustration with my wife, I had an idea. I started over, but this time I set up a brand-new account. Different ID, different e-mail address, even a different credit card. (But the exact same name and address.)
This time it worked, although it was rather slow to respond. At the end, I was asked to fill out a survey concerning my experience, which I did. Oh BOY, did I!
Flash-forward to yesterday when I received a call from a Newark representative, who was calling to welcome me to Newark and thank me for placing my FIRST order.
I informed her that it was NOT my first order and then proceeded to detail my recent experience. She seemed sympathetic and tried looking up my original account, which for some reason couldn't be found.
She then asked if I had any other concerns and I mentioned how I often find it difficult to locate parts in their system. She asked whether I was searching by the manufacturer's part number or Newark's part number. I told her, "The manufacturer's, of course."
She suggested I might have more success if I tried searching using Newark's part number.
I thought about it for about half a second and asked, "And just how am I supposed to know YOUR part numbers? I don't think God Almighty knows your part numbers."
There was a long pause and she finally acknowledged, "Yeah, that probably wasn't a very good suggestion."
However, she did tell me that they're rolling out a new website in a few days and it should be much better.
