Does anyone know what the maximum transaction value that a LU
touchscreen machine can transact?

Following on from my other thread, I tried to buy/renew an annual zone
1-3 travelcard this morning - only to be told that £1208 was above the
maximum value that the machine would authorise and it cancelled the
transaction.

This should make Monday morning interesting at Southfields given there
is no ticket office there..

btw: Can the Oyster Helpline (0845 330 9876*) still accept Customer
Charter Refund vouchers for telephone transactions?

*which seems to be publicised a lot less now as a method to buy
tickets
