We pay Norton Shopping Guarantee a substantial monthly fee to test and monitor our site to verify it meets the highest security standards. As part of our agreement with Norton, we also purchase an insurance policy on your behalf for every order placed on our site, that provides coverage for low price guarantee, identity theft protection and a purchase guarantee. It’s an added expense we take to make sure our customers not only feel safe, but ARE safe purchasing with us. The guarantee is visible on every page of our website, including product pages, shopping cart and checkout process.
You were not signed up for any service, save the one time use insurance policy we purchased for you, and you are not on Norton’s mailing list, this is Norton alerting you to use these free benefits if necessary. The email is the only one you will receive from Norton, and was simply providing you the proof of insurance and the mechanism to file a claim with Norton in the unlikely event that an issue arose.
Hope this helps, if you have questions please let us know, thank you.
