crobb305, because you don't know any merchant that allow this shows that you don't know what happens when you get lots of traffic and shows how ignorant you are because of what you haven't been exposed to.
I work in competitive areas such as travel and finance - for example most travel agents allow you to scrape their site and give you a special url to do that.
But you wouldn't know that because you are small time and think that is how it works for everyone and judge accordingly without knowing. I would expect 11+ years you would have got an idea.
