USA Kindle customers
Recently I’ve had complaints from two American friends that when they tried to buy my books on the US Kindle store they were being redirected to the UK store, which can’t sell to US customers. I took it up with Amazon and this is the response I received. Anyone who takes this route, please let me know if it helps.
‘Regarding your inquiry about US customers getting redirected to UK Kindle store while purchasing your book in our US Kindle Store, we suggest that you ask them to contact our Customer Support department at the below numbers.
— U.S. and Canada: 1-866-216-1072
— International: 1-206-266-2992
They will be able to help your customers in fixing this issue.
I hope this helps. If there’s anything else we can do to help you, please write to us at kdp-support@amazon.com.’
