Somehow, I think that using Amazing Prime costs more money because you see “free shipping” and actually spend more money. Today, I was a DVD that I wanted on sale in a Facebook post. My first thought wasn’t “what’s the cost” it was, “hey, I get free shipping”
It really is a great program though because it’s more than just free shipping. You get free videos, Kindle books, and much more. BUT, don’t let that free shipping seduce you into spending more money.
