On the one hand, visitors do tend to associate cost with quality, so with low price a surfer may think that the quality of product is accordingly low and may be reluctant to signup. In this case increasing the price may bring really good results.

On the other hand, it doesn't necessarily mean that the higher you put a price the better the convertions are. There is always a certain price limit and if you go above it you may hamper your convertions considerably. So I strongly believe that you need to make certain tests with different traffic sources to see what works best for you.
