Newegg offers a Newegg Premier 3-Month Membership for free via its app for iOS or Android. (Touch the promotional banner inside the app and enter your email address to get this deal.) That's a $20 savings and the tied with our November mention as one of the few offers we've seen for a Newegg Premier membership that isn't limited to students. It provides free expedited shipping on select items, exclusive deals, free returns, and other benefits.
Note that the coupon code you'll receive via email can also be applied toward a 6- or 12-month membership.
