Interesting! Thanks for sharing! DoorDash just started working with Costco in the USA a week ago. So this makes sense. https://about.doordash.com/en-us/...artnership

Until now it's been Instacart only…

What I do NOT like is DoorDash's disclaimer which requires waiving your right to a jury trial…

The real question is what the surcharge is on Costco items through doordash. With restaurants I generally thought that with the 20% discount on gas at Costco I'd basically be paying the same price I would have if I'd ordered at the restaurant.

It's up to $50 off, so spend $250 for most benefit

Says nearest Costco is 2,200 miles from my home (I'm near San Diego) and so doesn't let me shop.

Added $56 worth of products. Total at checkout after "discounts": $90.10. If I use this hack, which my account is ineligible for, the total is $57, requiring me to link my Costco membership.

I saw this bug too. Once you add your Costco card and then start a new search it seemed to go away.

Looks like about $2-3 per item in my area. So maybe a 20% markup. Doesn't seem worth jumping through the hoops.

"Get 20% off on orders $100+ from Costco. Now - 11/1" Maximum $50.

And it looks to me that the Doordash prices are about 10% more than the in-store Costco prices. I checked 3 items I regularly buy to tell.

The prices in Doordash are about 10% more than instore Costtco prices. e.g. the roast chicken is $5.55 through Doordash vs $5 in store

I pay $99 for $103 worth of Costco items after all the fees and crap. This feels like me helping them to pump their books, so I better pick some call options on the way.

You need to purchase through DoorDash app and there we don't have gift cards in Costco list so cannot double dip
