I used to feel the same way, until I got a job as an IT manager at a company, and a big budget. I still like prices posted on web sites, but I won't buy something without talking to a sales-person.

My job depends on making the right technology decisions. I'm not just going to buy based on the price list, I'm going to buy a custom tailored product with the right price for me. And I need to talk to a sales person, and I want them to be good at selling and I want them to convince me. If a company can't be bothered to hire good sales people then they probably can't be bothered to hire good support people, or programmers either.

Enterprise is different.
