head down to HSBC on monday and open an account or a 2nd account if you already bank with them, they promise to get you up and running in 7 days. that includes you pin, cash card, cbook and one other item that eescapes me right now, if they fail to deliver any of them within 7 days they pay you £10 per item, working out to be £30 - £50 depending on what you ask . with the postal strike that's a gimmie if you head down on monday
