The Offer

Direct link to offer

  • Costco is offering $15 off $50+ on same day delivery orders when you use promo code WINTERSAMEDAY25.

Our Verdict

Need to be a Costco member to take advantage but still useful. Scheduling delivery worked last time. It will also accept Instacart gift cards that have been on sale for 20% off recently.

Prices on Costco same day showing about 10% higher compared to ordering same stuff from instacart website costco. Strange. It used to be other way around in the beginning. I have membership for both Costco and Instacart. Not sure if thats making the difference.

if you link your sameday to instacart account, it will show the same unit prices as instacart

I always tip so I probably just came out even on this deal but did like the $2 off with the no-rush. The prices are hiked up as if you are ordering on doordash.

You can get additional $2 off if you choose no-rush 3 hour delivery window.

If we wait until June 30, then this should stack with the new $10 off for Exec members?

That’s great that this deal comes back for almost a month! Normally a code like this is only good for a long weekend

The protein I buy is on sale at the Costco website, but It’s $15 more through the link. I also read about tipping the delivery person. How do people get the most out of these promos?

They generally just waste your time and money. Ignore them unless you need something today but can’t drive there.

Disagree. If you truly value your time, these discounts (plus the instacart gift card discounts when they’re available), make it a no brainer to order here and avoid driving to the store. Avoiding dealing with the Costco parking lot and lines is very valuable to me.

you buy discounter instacart gift cards and use those. You used to be able to buy from Costco for 20% off, but sadly that ended. You can still get various places for 10-15% off periodically. With the 20% off it basically made ordering sameday the same price as going into the store after tip/fees, now it only is worthwhile when we get these promos (or if you really don’t want to go into Costco)

I only use this promo when it’s $25 off and use discounter instacart gift cards to pay or if there is offer on Paypal. Otherwise, not worth it.

You can usually double up on this by placing an order with Costco and Costco Business.
Be careful not to adjust your order after placing it in any way or you will lose the promo permanently.

Also, Chase has a 5% back on instacart offer for Freedom cards through MyBonus. It shows up as “Costco by Instacart” on my CC statement. Don’t know if it codes for 5% yet.

Yea, Costco Business has a separate promo code for $15 off $50. Let me add.

Sadly Costco nor Instacart shows up for my Freedom Unlimited card.

I was wrong about losing the promo permanently. I made a change to my order and lost the discount, cancelled and attempted to place again. Discount didn’t show up in checkout and promo code said it was already used.
A day later it now shows up in checkout.

if you use this offer one time are you locked into a contract and for how long?

no this is not related to Instacart+. If you subscribe to that you pay $79/year after the free trial, and you get ~5% lower prices on everything. but you don’t have to be a Instacart+ member to use this offer.
