) was the cheapest to the UK i found.
$20 for 1 bottle and $7 for shippping, opposed to global light who i think charged $40 for shipping.
There are several US sellers on ebay shipping to the UK and selling a bottle i think for $11 and shipping about $8 but thats upto you if you want to buy off ebay.
There are of course UK sellers on ebay selling Miracle-Mineral-Supplement
but to make a profit they are selling bottles for £20 each which of course is more like $40. Gotta love this rip-off country.
