Does it automatically geotarget or will it only display US items if you make it on a US account and vice versa for UK. Thanks
aStores displays the product/categories you picked, aStores from US affiliate display only Amazon US products and so on...
If your aStore is on an amazon.com affiliate account, it will show amazon.com products (although people from all over the world can buy from there). Same with a UK, Canadian, French, German etc. affiliate account. I am in the UK but I could still buy from the US amazon store, which i most likely wouldnt do unless there was a product i really wanted (different amazon sites have different product ranges). What I normally do is setup a UK and a US store, and geo target between the two. You can't do this purely with aStores, you would need to have your own site as a "landing page". The best you can do with aStores only is to link between the two, via the about page or the 1 x link you are allowed to put in.
