Just this week I encountered this exact thing

On Sunday (first workday here), I needed a PoE injector that could take in 24V DC and step it up to PoE+ voltages (around 50V iirc), so I looked around, and found an industrial one that matched my requirements. On the manufacturere's website, there was only a GET QUOTE button, and when searching for the model number, I couldn't find a place where I could just buy the thing.

So I clicked on GET QUOTE and filled in my details, company, work email, etc.. I then got an automated email saying my request was received along with details of the request (just the one PoE+ Injector).

We needed this for a fairly tight deadline, so we ended up getting an industrial PoE+ switch, which also gave us some added flexibility, and had 2 units on my desk by Tuesday.

Fast forward to today (Thursday), I get a call from a local distributor who had _no idea_ which product I requested a quote for, and just asked about what my needs are. I of course told them it's no longer relevant, and they decided to send me an email with some wildly irrelevant brochures for ruggedized tablets.

All this is to say, if the manufacturer just put up a price or link to buy online, I would have likely ordered 1-3 units on the spot, either directly or via a distributor. But they decided to complicate the process, and lost the sale to someone who was willing to just sell the products instead of trying to get me on a call.

I also had a look at the distributor's website, and they seem to offer various vague "compute platforms" and "industry-specific solutions", I typed in the model number into the search box, and got no results, and when I typed in the manufacturer, it just brought me to a page saying they are a "Platform Partner", with another contact button.
