It's been consistently shown that what people say they'll do regarding pricing and what they actually do are not correlated.

Rather than asking people, if you can, try just changing the prices and see how customer acquisition changes.

I sell a program online to consumers, so for a while I tried several experiments in pricing, including a "pay what you want". Structure. Eventually I settled on a price that's about half what the highest accepted price was ($10) and the typically "pay what you want" price ($1). Right now I sell for $4 (perpetually listed as 50% off of $8), which brings in about as much revenue as the $10 price. The advantage, though, is that it gets in the hands of more people, so there's a higher potential for word-of-mouth advertising.

So, I would say, if you're in the position to do so, experiment with the prices in the real world and look at how purchasing behavior changes.
