Fio de Sal is a homewares retailer in Aveiro that ships ceramics, linens, and small décor items to customers across borders. It joined No Bill at the Door after several buyers asked whether import duties might still be due when a parcel arrived. The retailer now checks destination requirements at checkout and displays applicable duties and taxes before customers pay whenever those amounts can be calculated. If a destination charge cannot be determined in advance, the order page explains that limitation before purchase instead of leaving customers to discover it at delivery. Staff updated the confirmation email too, so the cost information is easy to find later. In the first three months, delivery-related billing questions fell from 11 to 3, and the rate of refused international parcels dropped from 5 percent to 2 percent. The owner says transparent landed costs help customers make an informed choice and reduce avoidable stress for both the buyer and the small team.
