Thank you for shopping with latrand.com. This policy explains how we ship your order, what it costs, and what to expect after you buy.

Order Processing

Except as otherwise stated on our website, orders are processed within 2 business days (excluding holidays).

Orders placed on weekends and holidays may begin processing the next business day.

You'll receive a confirmation email with tracking as soon as your order ships, if the shipping method supports it.

Shipping Methods & Delivery Times

Available shipping methods and the final shipping charge are shown at checkout. Estimated transit time after dispatch is 3–5 business days within Bulgaria and 5–8 business days to our supported international destinations, in addition to order processing of up to 2 business days. Transit times are estimates, not guarantees, and begin once your order ships. They may be affected by carrier delays, weather, or other events outside our control. If an estimated delivery time is not displayed at checkout, please contact us before placing your order.

Shipping costs

Fixed standard delivery is €4.60 within Bulgaria, €6.90 to Germany, and €8.90 to the other supported EU destinations and the United Kingdom. Standard delivery is free on orders of €100.00 or more within Bulgaria and €200.00 or more to the supported international destinations. Other available courier options and the final shipping cost are shown at checkout before you confirm your order.

United Kingdom customs, taxes and other applicable fees

For orders shipped to the United Kingdom, taxes, duties, and import fees may apply. Where available, these charges will be calculated and collected at checkout. If taxes or duties are collected at checkout, they will be shown before you place your order. If these charges are not collected at checkout, they may be due before or at delivery and are the customer’s responsibility unless otherwise stated.

In some cases, additional import charges, customs duties, VAT, brokerage fees, or carrier handling fees may be due when your order arrives in the United Kingdom. These charges are determined by UK customs authorities and/or the carrier and are the customer’s responsibility unless we expressly state at checkout that duties and taxes are prepaid.

Customs processing may also affect delivery times. We recommend checking your local import rules before placing an order.

European Union orders

Delivery to another EU country is available when that destination and an appropriate shipping method are offered at checkout. Available destinations are shown when you enter your delivery address.

International shipping charges depend on the destination and available shipping method and are shown before you confirm your order.

Bulgaria’s domestic delivery periods do not automatically apply to international deliveries. Please check the estimated delivery time for your destination before confirming your order.

Order Tracking

Once your order ships, we'll email you a confirmation with a tracking number and link, if applicable. Please note tracking information may take time to update after you receive it.
