20% off $100 DoorDash gift cards at Costco

Pay just $79.99 for $100 DoorDash gift cards when you buy them in-store at Costco or online on the Costco website.

There is a limit of three gift cards, though this appears to only be per transaction as I have so far bought six of them across multiple visits.

20% off is exceptionally good for DoorDash gift cards as the standard offer on these gift cards nowadays is only around 10-12% cashback or 20x rewards points.

For those unfamiliar with Costco, a paid membership (starting at $65/year) is required to shop there. You can also shop there as a guest of an existing member or if you hold a valid Costco Shop gift card.

Thanks to 1030510410 on OzBargain for first finding this offer.
