Keep in mind that there are ways for the merchant to change FC assignment or product configuration after order creation that could invalidate this estimate. Estimates cannot be returned for items that are unknown, out of stock, or too large for fulfillment using standard box sizes. Additional services such as high-pick fees, shipping insurance, auto-splitting or auto-adding items to orders, and signature required are not included in this estimate.
