How much is Touch interface worth to a newsagency?

I got this question asked to me by a newsagent at the Caulfield cup.

It is a difficult question to answer because it varies some much from merchant to merchant. A while ago, Touch told me that a good newsagency site does about $285/week in sales commissions.

However since we have established a new link with its much faster speeds and greater convenience; touch tells me that the rate has increased so I suspect the commissions are higher now.
