scmiami - I write something like this:
"I have been shopping since ________________ and am signed up with over ________ companies. In 2012 I did __________ shops (or last month I did ___________shops.) I cannot reveal the names of the companies due to independent contractor agreements."
So far I've been accepted everywhere, so this must usually be an OK approach.
