I don't know if the problem has been resolved since 9am, but first thing this morning M&S on Lordship Lane were not able to take card payment, only cash. This issue was compounded by the nearest cash machine at the P.O. being out of order. I also heard a number of M&S staff say that Sainsbury's at DKH were also unable to take card payments. I managed get some cash out of the Co-Op ATM in the end.
