Oliva de Barrio is a Seville shop selling olive oil, preserves, and gift parcels from small regional producers. It took the No Bill at the Door pledge after a customer received an imported serving set with an unexpected collection charge and assumed the shop had hidden part of the price. The business now reviews shipping routes before confirming an order and shows estimated duties and import charges before the customer pays whenever that information is available. If a charge cannot be calculated precisely in advance, staff explain the uncertainty and obtain the buyer’s agreement before proceeding. The shop also added a plain-language note to its order confirmation, so customers know what is and is not included. In the first ten weeks, 27 international orders were completed with estimated duties disclosed before payment, and none resulted in a surprise-charge complaint. The owner says the pledge has encouraged the team to be more careful about cross-border orders and to make a clear choice available before checkout.
