I use Clinitas Ultra 3 which is the UK version of Freshkote, it is available over the counter and is £8.50 (about $17).
Much more cost-effective than the single-use drops and I've been told the mild preservative it has is suitable for long term use.
Be careful though, with all of the bottled drops, you should only use them within 28 days of opening otherwise you are risking an eye infection.
I don't know about international shipping costs but I have only good things to say about the deliveries I've had from Matheson's:
