You are responsible for covering the return shipping costs.
To avoid these costs, you can opt for the refund to be credited to your Client’s Balance.
If you select this option on the Return Form, the refunded amount will be added to your account and automatically applied to your next purchase.

You can ship your package on your own with any delivery service you choose.
(Available only in Poland) You can also send it with any Parcel Locker Paczkomat® ® InPost using our return code – remember though that if you choose the Cashback return option, the amount will be reduced by the shipping cost.

Keep in mind that we don’t accept pay-on-delivery shipping.

Your refund will be processed within 14 days following the receipt of the returned goods, although the process is often expedited and completed in a shorter timeframe.
If you have been issued an invoice for the products you're returning, we are required by accounting regulations to obtain your acknowledgment of the credit note before proceeding with the refund. Consequently, the return will be initiated after we receive this confirmation.
In instances where the original delivery was paid for on delivery (cash on delivery), and you opt for a bank account refund, please ensure to provide us with the bank account details where the refund should be directed - You will do it while filing your return form.

Correct return address for products is provided after completing the Return Form, which can be found at the bottom of the form once filled out.

To exchange an item, please initiate a return for the unwanted product using the Return Form, and then place a new order for the item you wish to receive instead.

Please note that to be eligible for a return, the product must be in its original, unused condition and must not show any signs of wear or mechanical damage. Additionally, all original labels (stickers) provided at the time of purchase must be intact and unaltered.
Products that do not meet these conditions may be subject to a reduced refund value or may not be accepted for return.
This policy is in accordance with the [applicable law/regulation], as published in the Official Journal of 2014, item 827.

If you decline a pay-on-delivery package, it will be sent back to us. You'll have 3 days to decide if you want us to resend it. Should you opt for resending, please be aware that you will be charged double the shipping cost.

If a pay-on-delivery package is rejected a second time, we'll remove the cash on delivery option for future orders. You will then be required to use advance payment methods. This policy ensures all cash on delivery orders in Poland are processed smoothly and without unnecessary delay. Note that the pay-on-delivery option is only available for orders within the territory of Poland.

  • Take detailed photographs of the device from every angle, ensuring you capture all sides comprehensively - aim for up to 20 photos to cover the entire device thoroughly.
    Store these photographs securely as they serve as a record of your device's condition before shipping.
  • Pack the device with extreme care, using ample protective materials such as bubble wrap, foam, or other cushioning to safeguard it during transit. Place it in a sturdy, appropriately-sized shipping box to prevent movement and potential damage.
  • Please be aware that we do not assume responsibility for any damages incurred during the shipping process. Your documented photographs will be your proof of the device's condition prior to shipping, which is important in the unlikely event that it arrives with damages caused in transit.
