Spedizioni in Italia
La spedizione è sempre gratis per acquisti superiori a 50,00 euro.
La promozione non è applicabile per le spedizioni in CONTRASSEGNO.
Per alcuni prodotti è opzionale l'aggiunta dell'assicurazione (per prodotti molto voluminosi e costosi).
Spedizioni estere in Europa
Per le spedizioni in paesi europei bisogna contattare a mezzo mail il nostro responsabile che vi indicherà in base all'oggetto scelto i costi e tempi di spedizione (approssimativi). Se si effettua l'ordine inserendo come indirizzo di spedizione una località estera europea, il nostro personale appena visionerà l'ordine invierà una mail con il costo della spedizione aggiuntivo da aggiungere al relativo ordine, il costo sarà cosi' sommato all'ordine e reinviata una mail di conferma che permetterà solo in quel momento al cliente di poter eseguire il pagamento con la modalità scelta.
• Quanto tempo occorre per la consegna?
L'ordine sarà evaso entro uno/due giorni lavorativi (ove il prodotto sia disponibile) a partire dal giorno in cui l'ordine verrà perfezionato.
L'ordine è considerato "perfezionato" nel momento in cui:
- conferma di ricezione del pagamento attraverso le varie modalità possibili (mail :info@audioevolution.it)
• Come faccio a rendere la merce difettosa?
Basta mettersi in contatto con noi spedendo una e-mail all'indirizzo: info@audioevolution.it
• Spedizioni assicurate
Per assicurare le vostre spedizioni, vi chiediamo cortesemente di contattarci per conoscere i costi precisi, consigliamo vivamente di assicurare la vostra spedizione.
