I suppose you just have to choose what angle you want to come from. I've noticed most commercial photographers, the high end guys who shoot Pepsi and Nike ads don't list prices. They don't have to. Their clientele doesn't care how much it costs and expects to pay a certain amount. In fact, I suspect Pepsi and Nike determine the price scale.
The rest of us? Should be upfront about pricing.
As a recent bride, I can impart my experience on both sides of the fence - as a shopper and a photographer.
Price was most certainly an issue. If someone didn't list their prices, I moved on. When I found a photographer I absolutely loved, I checked her prices and realized I couldn't afford her. My instinct was to NOT haggle. I felt like it would insult her, so I posted an ad on Craigslist and found a great photographer in my price range. I was happy with the results. However, as a photographer, I knew what to look for. In my experience, brides have no idea what to expect and they want their vendors to lead the way. For those few brides who know exactly what they're looking for and money is no object, they are few and far between. Most brides have a strict budget they adhere to and just want someone good/great for a reasonable price. They want more bang for their buck.
