Are we supposed to still add a tip, even though we're going through costco sameday and not using instacart directly?

"We" know it's still a delivery service.

Just like any other delivery service, it's up to you on your own personal tipping preferences and amounts.

Who's "we"? I didn't.
Given that I need a Costco subscription and $35 order minimum, I don't expect to tip at all.
If I use the instacart app, now that's a different story.

Yes. It gets shopped and delivered by instacart.
