Clamato Juice

[Jinglepot]

Can anyone tell me where I can buy Clamato Juice in Co. Antrim please?
I phoned Sainsburys who said none of their stores had it. I also phoned the local Tesco, Asda, Supervalu and Co-op without any luck.
What could I substitute for making clam chowder if it is unavailable?

You MAY find it online.....there are a number of sites that sell 'American groceries'...just google that.....

......or-mix V-8 juice (available in Sainsbury's and Tesco) with the juice of tinned clams.

Thanks pastafreak, I had checked the online shops but they work out too expensive unfortunately. I have in the past used V-8 with the clams but they are in brine so a bit disappointing really.
I wonder if I added a 1/2 of a fish stock cube would that work do you think?
Many thanks for your help.
