I've been a customer since 1996. Yes, for the books. Stopped being customer around 2017 when I noticed a significant markup on all Amazon items. Almost any item can be found cheaper at ebay, aliexpress or somewhere else. Haven't bought prime because I oppose to customer lock-ins and to monopolies in general.
