@Se_Railway one of your staff members, Ahmed (working at Canterbury West station), helped me locate my suitcase that I left on the train. He was so kind and reassuring throughout- please let him know!
@Sophiegoddard Vinted is best for quick and cheap sales (You never see many bits for over £10 on there!), Depop is a waiting game and can take months, but you normally get slightly more £££!
