Martin Lewis has issued a stark warning to anyone getting married during the ongoing coronavirus pandemic. The financial guru appeared on This Morning recently, where a caller had a query about booking a wedding venue.She claimed the venues were refusing payment via debit or credit card so asked Martin whether she should simply pay by bank transfer (BACS).But he was quick to shut down that possibility.“I have to be plain and this isn't what you are going to want to hear,” he said.“I would never pay for a substantial transaction in BACS.“BACS are bank transfers and they have no protection.
