Doesn't seem to be a clear portal just for the 15% gift cards, and most of them are restaurants, but there are some solid brands in there aside from those in the title including Sheetz, Barnes and Noble, Lyft, Stubhub, GameStop, and PetSmart. DashPass members only. Valid from today, 7/10/25, to Wednesday 7/16/25.

15% discount will max out at $25 off, or $166.66 of gift card, but don't buy the same amount twice, as that tends to result in errors and transactions getting declined. Usable twice.
