I think Amazon Prime membership is well worth the money. Shopping, shipping, video, reading, etc. I’m a supporter. I don’t think they are any better or worse than any large company. I just look for value for my money. And convenience has a high value to me. Amazon delivers...both literally and figuratively imo.
And a Kindle Paperwhite is going to be hard to match, especially if you like to read late in the day...very easy on the eyes.
