Right now on Groopdealz you can grab Spring Yeti Tumblers (6 Designs) for $26.98 shipped! My readers have purchased these several times- they seem to work as well as Yeti but the design on the outside does void the warranty. The conclusion seems to be unanimous that they are not official YETI products.
Groopdealz has a new pop up where you have to put in an e-mail address before they will let you look at products. I put in [email protected] and they let me in. Feel free to do that so you can look at this without giving them your e-mail.
