Theres never a dull question from your good self!! Any chance of some
feedback sometimes? Well, lets look at the numbers, if there selling
for 10 there buying for 5, the makers will have costs of no more that
for the bottle, water gold and distribution.
So the gold is likely to be less than 20 cents, if that.
the only way to find out is to buy one, recover the gold and weigh
it. tho I doubt if that small amount is weighable even on a good
micro digital scale.
Are you supposed to drink it? If you want gold, your best source is
scrap electronic circuit boards. There be lots more gold on those
than in the water.
A pain to recover tho.
