Are you able to find it by searching amazon.co.uk directly? I just tried and it didn't come up either, which may explain why so.cool is not picking it up either.
Yes. Just type multivitamin, then click Filter and then Sort by average customer review. It comes on top.
Hmmm... I don't see it when I do just what you described. Here is my guess: I noticed that when I open the direct link you posted above the page states that "This item does not ship to the United States." I wonder if Amazon servers detect that the search request is coming from the US (that's where the so.cool servers are located) and is excluding the items that are not available to the US buyers. Not sure if there is anything I can do about that, short of buying a server in each country that the site searches. Sorry!
I am from UK and use co.uk So there is no workaround for this? Doesn't this mean that any item on an Amazon site other than .com that doesn't ship to USA won't show on so.cool?
This is the first time I see anything like this and it is only a guess, so I can't say with certainty. But yes - possibly so.
