Three of us are coming down to London on the 7th September (Arrive on
the 8th at 6.15am - Victoria coach station) from there we're going to
Hornsey then around and about zones 1-3 until Monday when we need to be
back at Victoria for 12.30.

From looking at the tfl website, I think my best option for tickets is:

Friday : Peak travelcard zone 1-3 £7.20
Saturday: Off peak travelcard zone 1-4 £5.40
Sunday: Off peak travelcard zone 1-4 £5.40
Monday: Peak travelcard zone 1-3 £7.20 *or* Off peak travelcard zone
1-4 £5.40 depending on when we leave Hornsey.

Can anyone offer anything better?

TBH I think you have the best option there, although if you're only
making a single journey from Hornsey to Victoria on the last day then
you will only need single tickets.
