Amazon offers its Prime members the Urban Armor Gear Case for Samsung Galaxy Note 4 in Rust (pictured), Black, Slate, or Ice for $21.39 with free shipping. (Non-members can spend $35 or more to bag free shipping; otherwise it adds $6.01.) That's the lowest total price we could find for this composite case by $4.
Orders placed via 2-day shipping today, December 22, will arrive in time for Christmas. (This option is free for Prime members but an extra $11.01 for everyone else.)
