Occasionally, we may run out of certain items. Within your cart, under “Item Preferences,” you have the option to decide if you want any substitutions. And, with certain product exceptions, you have the option to request a full refund for a substituted item within 48 hours of pickup of your order. Simply notify your driver or Store Associate at the time of pickup, or contact Customer Service at (877) 505-4040 for assistance. If you were charged for any items that are missing from your order, contact Customer Service within 48 hours from the time of pickup of your order. Note that certain items, including baby formula, alcoholic beverages, and tobacco products cannot be returned or refunded once you have accepted  picked up your order. If you elect to use a third-party delivery service (such as Rush Delivery by Instacart), your order will be subject to the substitution and refund policies established by that company.
