I just wanted to get everyone's opinion on this, so I've been thinking about using a cookie I set on our ecommerce site to show customers different content when they return to the website. It is pretty simple to setup and I can set the expiration date far into the future to ensure that the cookie will present. What is everyone's thoughts?
EDIT: Just wanted to add - no personal information is stored in the cookie, only information about the source offer. So say the customer signed up through a Walmart promotion, they would be cookied and once they come back to the site - we read the cookie and show a welcome message for walmart customers
