right, so my oyster is due to expire on saturday coming. quite niftily,
oyster had sent me an email telling me so - i didnt really have an idea
myself.

now, usually id buy my ticket on the monday, since i woudnt be using the tub
on the sunday. is it possible for me to do that now? or does the renewal
force me to start it on sunday?

if i /do/ commit to a monday start, is there any way i could bring it back
to sunday if i find i need it then? im really uncomfortable buying TCs in
advance i guess....

whatever i decide, what are the experiences with getting your card reloaded?
has anyone missed it (by travelling from a different station or the like)?
what happens on the bus if its not renewed in time?
