An article in thelondonpaper this evening states that the £3 deposit
for obtaining a new Oyster card (currently only payable if using PAYG
or buying a weekly season ticket) will, from May, also be charged when
buying a longer-than-weekly season ticket.

When did the £3 deposit start being implemented for weekly tickets? It
didn't used to be.

I could be wrong. I thought that, for some time, fares leaflets stated
that it was payable on weeklies, but as a sort of temporary special
offer, it wasn't actually charged. Perhaps this just became permanent.

The article did say the deposit would be introduced on "season tickets
for longer than a week" rather than just "season tickets", though.
