I think the info you are after is perfectly legit and should be openly shared. You're not running a government probe into a private business trying to decide is their profit margin "fair". Educating the public on the products you offer and why they are superior to another company's is good for business. So I like what your trying to do. The only thing to suggest is to maybe watch the tone or wording. It's difficult at times to fully understand someone when all you see are words on a screen. All the nuances of the human voice and demeanor are lost. If you're not out to slam a business and are just probing for legit info, what's the problem?
