No. Your Costco Same-Day Delivery cart is separate from your Costco.com cart, so you cannot purchase Costco.com items and Costco Same-Day Delivery items at the same time.

Instacart puts a temporary hold on your credit/debit card that includes a buffer to take item additions or substitutions into account. The final charge represents the items picked, and will not include items cancelled due to being out of stock.

Back to Top

You may see a temporary hold on your account before the final charge reaches your credit/debit account. The temporary hold should show as "pending," and will be removed within a day or two.

The Costco Shop Card cannot be used as a form of payment for Same-day Delivery powered by Instacart orders. If you would like to use a Costco Shop Card to pay for your order, we recommend utilizing our 2-Day Delivery option.

To request a refund for any reason, you must make your request within 7 days of delivery. Please let Instacart know as soon as possible if your order:

• Is missing items that you were charged for on the final receipt
• Contains damaged, spoiled, or otherwise unusable items.

Refunds issued by Instacart are processed immediately, but it may take 5-10 business days to see the funds in your bank or credit card account, depending on your bank. You won’t see refunds in your Instacart account. You can also return items directly to a Costco warehouse for a full and immediate refund.
