Hi folks - quick question.

I will be getting an annual zones 1-3 on my Oyster very shortly - what
are the advantages of having an annual season ticket other than the
reduced cost? Does it entitle you to any discounts etc?
If so, should I go the paper ticket route so that I can "prove" that I
have an annual ticket (given that you can't tell from just looking what
period an Oystercard is for? :-) )

Any advice appreciated

Many thanks
