Eeeek, I should take that back (although I still think there isn't a Coca-Cola Blonde).
It appears there are some wierd Coca-Colas out there.
They have Coca-Cola Blak, with coffee in it. They sell that in the US though... (One Al bottle here costs £1.56 and one can is £1.10!)
And theres Coca-Cola Sango which is Coke with a Blood Orange Flavour (1 Can: 90p, 12 Cans: £9.99, 24 Cans: £18.99), which is normally only available in Belgium and Luxembourg, but its imported to the UK. It would be expensive to ship though
I think they also do/did Coca-Cola Rasperry, but that was a limited edition Coke from New Zealand, and is out of stock from the importers in the UK.
And then theres the Lime, Lemon, Cherry and Vanilla ones that everyone knows about...
