• Find the Discount Code or Promo Code field.

• PayPal
• Visa

• Discover
• Diner's Club
• Apple Pay
• Google Pay

Available payment methods may differ depending on your location or region.

How much does shipping cost?

Our standard shipping fee is generally USD $5.99.

Actual shipping charges may vary based on your delivery location, selected shipping method, or current promotional offers. The applicable shipping cost will be shown at checkout before you complete your purchase.

2. Shipping & Delivery

Does Eucallos offer international shipping?

Yes.

Eucallos ships to customers across many countries and regions through our international fulfillment and logistics network.

How long will my order take to arrive?

Once your order has been processed and dispatched, estimated delivery generally takes 10–20 business days.

Actual delivery times may vary depending on your destination, customs processing, weather conditions, and local courier operations.

How do I track my shipment?

After your order has been shipped, a shipping confirmation email containing your tracking number will be sent to you.

You may use the tracking number on commonly available parcel tracking platforms to follow the progress of your delivery.

Why is my tracking status not updating?

Tracking updates may take 24–48 hours to appear after your shipment has been dispatched.

For international orders, tracking information may also remain unchanged temporarily while the parcel is moving between logistics facilities or waiting for its next scan.

Why did I receive my order in separate packages?

Some orders containing multiple items may be fulfilled from different warehouses or fulfillment centers.

As a result, your products may arrive in separate packages. When this happens, separate tracking numbers will be provided for each shipment by email.

3. Order Changes & Cancellations

Can I update my delivery address after ordering?

If your order has not yet been shipped, we will make reasonable efforts to update the shipping address.

Please contact support@eucallos.com as soon as possible using the subject line:

Urgent: Address Change

Please include:

Once an order has already been dispatched, we may no longer be able to change the delivery address.

Can I change the products in my order?

If your order has not yet entered warehouse processing, changes to the products may still be possible.

Please contact support@eucallos.com as soon as possible and provide:

• Order Number
• Email Address
• Details of the requested modification

We cannot guarantee changes once order processing has already begun.

Can I cancel my order?

Orders may be cancelled before they are shipped.

Once fulfillment or processing has begun, cancellation may no longer be possible, and a handling fee may apply where permitted.
