I'm with suginami and el chivito. Been a member for years and an extra 20 clams isn't going to change my mind.
Just being able to get a competitive price on many items, without having to go into public at a brick and mortar establishment is worth the price of admission.
Getting the stuff in 2 days for no added cost is icing.
The free prime videos is over the top.
We've pretty well worn out most of the video selection now, but occasionally we'll buy one and let Amazon store it for us in the cloud.
My very first purchase with Amazon prime (I had gotten a free membership because I belong to Amazon Mom....
) was a bigger window unit air conditioner which we felt we had to have before the in-laws came for a summer visit.
I chose the $3.99 overnight option... figuring for sure that they would never overnight a 75lb AC unit for 4 bucks...
Next day it was on my doorstep, and I've never looked back.
