Sounds like buying the Prime feature is just for the free and fast shipping. They keep having prompts for me to use Prime.
I thought some had used it, not just for the shipping or the movies but do not know what else they liked.
In my case, paying shipping on used books, they do not even send anything out for at least 3-4 days. I just cancelled an order last night that was entered on the 11th, not in the process to ship. Wonder if they do that to 'make' people do the Prime.
Thank you for the replies.
