Email support@gema-net.de as soon as possible with your order number, order email address and requested change. Our team checks what is possible at the current processing and dispatch stage. Sending a request does not itself confirm cancellation or a change.
Enter discount codes in the relevant checkout field. Check spelling, expiry, minimum value and product restrictions. Special prices, combined discounts and retrospective credits need individual confirmation.
Any statutory withdrawal right remains unaffected by the processing of your request. See the shop's withdrawal policy.
