I don't, and I don't even deal with Amazon anymore. Back when I did, I discovered Amazon Prime used the 'bait & switch' tactic. I'd see lotsa items I wanted, but their shipping was overpriced, but free with Amazon Prime. So I'd sign up to it, go back to buy the items, and 'automagically' 80% of those items were no longer eligible for Amazon Prime free shipping. That happened a few times before I got wise to Bezos scam.
