For Amazon one can take one of two strategies forward:
1) Create copy that is very specific to a single item, that endorses the choice a potential purchaser has already made, in which case I would add the price. You expect a sale from anyone that clicks through in this circumstance - whether you get it is another matter.
2) Make an affiliate marketing page which compares and contrasts various similar models / products, in which case I would leave the prices off. You just want them to click through.
What one tends to find (particularly in the second scenario) is that, no matter what you write about, the potential customer goes off and purchases products completely unrelated to that which you wrote about. For that reason ones only task really is to get people to remind themselves that they can get what they really want, at Amazon. Just 'click here' should therefore suffice.
