I switched my Amazon digital account to Amazon Canada from the US site recently, primarily to be able to try Kindle Unlimited, which has been running a .99$ 3 month trial recently. My daughters English reading habits were starting to be an over $30 a week expense, and I thought this might present some cost savings, and perhaps encourage her to read more. I could already access Kindle prime, but the selection is even more pithy than Unlimited has turned out to be.
My hesitation to date has primarily been the mess that my 3 Amazon accounts (US, CAN, CN) presented to me when dealing with Alexa and the belief that the American store would always present the best selection of books. A cursory search has proven that the category of books I might be interested in, the selection is indeed less on the Canadian side and in some cases more expensive.
Of all the possible specific titles I might be interested in reading, none were available as apart of Kindle Unlimited. So I suspect, other than my fascination with easy reads from fantasy and sci-fi genres, this will have limited utility for me. Hopefully it might be of interest to my daughter and possibly Sheryl.
