I can't find the maple syrup in the UK :(

I really REALLY want to start the MC> I can't find grade B maple syrup anywhere here, I am in the UK. I checked health food stores, there is only stuff which isn't graded - with no ingredient lists on the label either. I know this isnt the correct stuff as it is not as dark as it looks on the picture.

Does anyone know where I can buy this stuff in the UK, or at least, online? I wanted to start this next week.

Thanks everyone..
