Each shop is having its own shipping policies, prices and estimated delivery time that varies by country. The estimated delivery date is when your order should arrive to your delivery country. Generally, the estimated delivery date is based on a combination of the processing time for the items you ordered (how long it takes the seller to prepare them for shipment), the transit time (how long the package is typically in transit with the shipping carrier), and today’s date.
To see seller’s processing time, go to Product page > Shipping or go to seller shop page.
The Estimated Delivery Date starts counting from the moment order is shipped, rather than when it’s placed. Therefore, If the seller marks the order as shipped earlier than the expected ship date, the estimated delivery date will be recalculated accordingly.
