Also, you can't top up smart cards for day tickets, so you'd still have to keep buying them online.

Cost comparison of Key V cash payment based on three day passes:
1 Zone Key = £13.20, cash = £14.55.
2 Zone key = £17.50, cash = £18.90.
3 Zone key = £22.24, cash = £23.40.
The Key is also useful when advance notice of a price increase is announced as you can top up your Key at pre-incresed price and store the tickets for future use.
Spot on, thanks for the info chaps!
