Amazon has done what many others dream of: I basically forget that I'm paying for Prime every year. And I perceive that it gives me enough value that I don't mind, but I've never actually checked how many orders I place each year vs. the delivery cost for them if I didn't have Prime.
By comparison, Google sends me an e-mail every month reminding me how much I'm paying for Google Play Music. I don't mind it, but I wonder if it affects their retention rates to do that.
