Just PM me the invoice
In all seriousness though, since it's considered opening a new line the salesman will be willing to offer really good deals. I went in expecting to have to pay $20 extra a month and $50 up-front for the thing... After some bargaining and a few changes to my data plan (no increase in cost -- increase in data available) I only had to pay $20 up-front and $0 extra per month for the added line. Just saying it could be worth a shot... you might be surprised. Having the auto hotspot connect makes getting started driving so much easier.
