I used a VPN and was able to purchase the $1 tier via PayPal and redeem the books to my Kobo account. When I was redeeming the code, I had to manually set the webstore to the United States. The books were added to my main Kobo library alongside everything else I own in there.

However, and this isn’t a big deal for most, you will receive the American English ‘prints’. Terry was so quintessentially English, it feels uncomfortable reading ‘Color’ of Magic rather than ‘Colour’.
