Apple's 2014 WWDC kicks off tomorrow with a Keynote at 10am Pacific. Today, attendees are registering for the conference and receiving their usual WWDC badges and WWDC jackets, but Apple also included a $25 App Store gift card.
The gift card is in celebration of "25 years and coding", as noted by @HarrisonW1998:
