It’s usually companies that aren't competing on price who want to keep price a secret. If a company doesn’t compete on price, they're probably competing on quality; customer service or other factors. But why avoid the question? Tell the visitor what your price is and even explain that it’s higher than the competitors–just explain WHY it’s higher. If you don’t compete on price and your visitor is shopping on price, then that visitor isn't your customer. Give him what he came searching for and sell him on your unique value. If that doesn't work, don't shy away from sending him elsewhere. That level of confidence is contagious, and often results in higher conversion, anyway.
