This is my first time posting, so please be kind or let me know if there is something I missed. Dave and Buster's is testing their new mobile app for iOS systems. Follow the link https://testflight.apple.com/join/yBbYJq12
from your mobile apple device to download the testflight app, then click on joining the beta testing. Once you register to beta test the app, add your power card or purchase a mobile power card. The first purchase you make using the app (there's a 24 hour count down on the offer) will be 50% off D&B normal chip rates. Chips get loaded on the card immediately after purchase. Requires iOS 11.0 or later. Compatible with iPhone 5S or later, iPad Air or later, and iPod touch.
I selected the Milpitas, CA location. Register your powercard, hit the "recharge" button for the registered card and the offer should show up.
$25 gets you 300 chips (12 chips per dollar)
$35 gets you 400 chips (about 11.4 chips per dollar)
$50 gets you 750 chips <--- best deal (15 chips per dollar)
Testflight code expires in about 84 days.
Save even more by going on a Wednesday when they have half priced games all day.
