I am getting emails for the benefit of REI, such as "REI Charging Backpack Holiday anti theft backpack" When I bought two clothing items at REI, I gave my email address but DID NOT GIVE PERMISSION FOR THIRD PARTIES TO SOLICIT ME. It is frustrating to get emails not signed by the sender. Unsubscribe is not supported without entering an email address. "http://kolmateris.com" is the web site that sends the unsubscribe request. The surface mail address for the unsubscribe is in Australia: See the following quote, "Click Here To Unsubscribe Or Write To: 501 Church St: Richmond VIC 3121" Long story short, I RECOMMEND do not share your email address with REI.
