I love Amazon for the convenience and selection. I have a monthly delivery set up (which gets an additional discount on each item) where I receive household items on the schedule I want (laundry detergent every three months, cat food every month, etc.) With this system, I never have to go to a place like Target, or buy cleaning supplies at the grocery store. I definitely save money and time with this system.
Initially I did buy books from Amazon and then the impact on publishing and bookstores became apparent. Ultimately, I realized there’s no reason at all to buy books when we have a great library system (physical and digital), so don’t buy books at all anymore…which obviously doesn’t really help bookstores and publishers.
