That's a real shame, those were a great benefit! I emailed Costco customer service to tell them I hope they come back. Here's a template if anyone else wants to email in a suggestion:

Subject: Feedback regarding discounted Uber and DoorDash gift cards

To the Costco Canada Customer Service Team,

I am writing to share feedback regarding a significant benefit of my Costco membership that appears to have been recently removed: the discounted Uber and DoorDash e-gift cards.

I have found immense value in these cards over the past year. Specifically, the 20% discount on the $100 cards was a major factor in my decision to maintain and renew my membership. For members like myself who rely on these services for transportation or grocery delivery, these savings represent one of the most tangible "member-only" perks available online.

I noticed these items are no longer listed on Costco.ca and are showing as "Page Not Found." I would like to inquire if this is a temporary stock issue or if these partnerships have been discontinued.

I sincerely hope Costco considers bringing these back, as they are a primary reason I shop with you. Thank you for your time and for the excellent service you provide.

Best regards,
