Through June 19, Google is taking 20% off the price of the Live Cases for the Nexus 5X, Nexus 6P, and Nexus 6. The promo celebrates Father’s Day, which happens this Sunday.

The promo shaves $7 off the normal price of $35 of the Places (custom location in Google Maps) or Photos (user selected photo) cases for the three Nexus phones. To get the discount, just apply the coupon code LIVECASE4DAD at checkout.

Google launched the first Live Cases back in May 2015, in a collaboration with dubstep demigod Skrillex. The current generation, featuring maps or photos, was introduced this April. At $35, they’re not exactly great value for money, but they are one of the more distinctive ways to customize your Nexus device.
