A complimentary voucher is a miscellaneous item in the Fallout: New Vegas add-on, Dead Money.
Notes
- You can redeem these for 1,000 Sierra Madre chips.
- One is deposited in the bunker drop box along with 100 chips every 3 days.
Complimentary vouchers cannot be redeemed unless you have won 7,500 chips at the Sierra Madre casino. This will unlock the code to redeem vouchers at the vending machines (a complimentary voucher will be added to your inventory at this point as well). If you do not do this before returning to the Mojave Wasteland, you will never be able to return to the Sierra Madre and consequently, the complimentary vouchers you'll receive every 3 days at the Abandonded BoS Bunker will be useless as the vending machine won't accept them.
Bugs
They may float in the air and you are unable to walk under it but you can jump on it, this can be exploited to make shelves wherever the player may need them and bridges if needed.
