I don’t think so Viccie. The banners are UK site only. We used to receive kickback from the US site as well, but the money went to a US based member who would transfer the money to us - it was very little indeed.
I'd happily go through the Amazon banner however I'm in France and post Brexit am naturally buying everything through Amazon France. If I clicked on the banner and then click again at the bottom of the page to the French site would you get the kickback?
It is mentioned in The Beginners Guide to Book Group Online , but is not very prominent, and I dont think any one bothers to read the front page. It has also been mentioned frequently when anyone posts a sales link to another site - but that is also probably not seen by anyone but the person who posted the link (and who probably never bothers to return to BGO thereafter)
The link on my computer that I use to access Amazon is copied from the banner at the top of the page here, so i don't even have to visit BGO to use it. I am hoping that means that everything I buy from Amazon puts a couple of pence into BGO's coffers.
