It's true that someone with your access and knowledge doesn't need something like this site. Most people are missing one or both. For instance, I don't have the access. And I'm a cheap bastard, so I'll probably do without before I pay what they're charging.

But I am not my customer. My customer is someone who has money to spend, but no time or interest for research, and would rather pay me for having done the research for them.

Anecdote back atchya:

I was once in a meeting with the CFO, IT Director, and National Processing Center Director. During the meeting it came up that the CFO was heading to our Nebraska Processing Center for a meeting. He hit Orbitz while we were talking. We got on a tangent about taking the earlier flight with a layover, or spending $35 more for the later direct flight. Ten minutes into the discussion I asked, "At our combined salaries, how long do we talk about this before we've spent $35?"

For lots of people it makes sense to spend $22 for a half-pound of buffalo jerky rather than spend two hours searching for a cheaper source. WalMart has built a business model on selling to cheap (or poor) bastards. That's not the business I want to be in.
