Making promo codes public to grow loyalty and long term retention

Bolt is one of the few apps that dare to make their promo codes available to all users. All applicable promo codes can be found on the promotions page, even if I have not redeemed them. Removing barriers to enter a coupon may impact short term business but participates in longer term retention: some users would not have ordered if there were no promo. This also participates into bringing the Bolt brand closer to their users.
