Right. The scenario you describe is reasonable. But as a buyer, if you put out those few pricing options, even if none of them match all my needs, I get to see both the features you offer and the prices you ask, which gives me the two critical pieces of information I seek: whether you have the capability to satisfy some or all my needs, and what order of magnitude we talk about in terms of costs. If that information tells me that you might have something for us, and it might fit in our budget, then I'll be more than happy to call you, and spend whatever time is needed to agree on a set of features and a price that works for both of us.

The thing I want to desperately avoid is wasting time dancing around the salesmen trying to overhype their product while staying vague on the details, in hopes to get me to buy (and pay as much as I can) regardless of whether I get any value from it.
