Would really love to have a similar script with no alert and a modal window, but I will try to tackle that myself, let you know how it goes. Thanks again for sharing with the rest of the community. And please do that jQuery version! Best.

on the 3rd page when they miss the offer maybe leave an email, b/c ppl will email when they know you are serious that it was a one time offer…they are more likely to take quick action and you appear more than just another pop up marketer, but rather offering a true discount

You can find the script below:

else var expires = "";
document.cookie = name+"="+value+expires+"; path=/"; }

function readCookie(name) {
var nameSG = name + "=";
var ca = document.cookie.split(‘;’);
for(var i=0; i<ca.length; i++) {
var c = ca[i];
while (c.charAt(0)==’ ‘) c = c.substring(1,c.length);

SCRIPT ENDED ABOVE

Thanks everyone for your contributions, If you have an addition to this script leave it here in the comments or send me an email! Thanks!

No worries! Thanks for the constructive criticism – This script has been very popular and receives a lot of use – and It is over 1 year old now, so I will soon be re-building this post to be easier to follow, and probably building a jQuery version of this script as well so it will be even easier to use – I just haven’t had a chance to do that yet! Thanks though for your kind words .
