In principle I agree with all you say Brandi but Amazon have been working for 25 years, with the complicity of governments, on building a monopoly and they’re hard to avoid especially for unusual items. Also we have to remember that for many small businesses selling through Amazon is a lifeline.
So in pragmatic terms I’d say avoid Amazon as far as possible, when buying difficult to source items from sellers in the Amazon marketplace check if that company has an alternative online outlet and buy from there. And if you have a Kindle … you’re just stuck with them.
