What browser are you using. Most will have a "pop up blocker" that you can activate that will stop "coupons" and any other spurious pop ups that may occur. I use Firefox and in the settings, the is a place to activate the pop up blocker. Check your browser for such a setting as I believe stopping pop ups is a function of your browser and not RV.Net.
