Ho comprato 2 lotti dallo stesso venditore e pagato 2 volte le spese di spedizione di € 85 per ogni lotto. Il venditore ha fatto una sola spedizione ma non vuole restituire le spese pagate 2 volte.

Vendedor excelente, muy amable y atento. Me encantó el regalo sorpresa. ❤️ Lo negativo fue el envío y los elevados gastos de aduana e impuestos. ¡Recomiendo totalmente al vendedor! 😊
