I have bought strips in a French territory, in the Tropics. They worked fine with my UK source meter. My understanding is it's the meter that applies the figure to the sample. I have felt confident that provided I could find the matching strips to a meter, I could sourest them anywhere.
If you go ahead, could you let us know how you get along?
You might want to check out any customs/VAT implications, as that could negate any financial saving, if you are buying over the internet.
