Amazon forcing acceptance of 30 day free trial of Prime

New Amazon scam.  I tried to buy items costing more than $35 expecting free shipping.  I got the usual offer of Amazon Prime free 30-day trial.  I turned it down. Then the site went to force me to take it.  No other delivery option was offered.  I could not make a purchase unless I signed up for Amazon Prime.

Even got someone on the phone and she could not understand why there was not other delivery options.  In fact, there were no delivery options at all.  Just the offer to sign up for free Amazon Prime for 30 days.  Take it or leave it.  I left the products in my list and will try to buy them another day.  Maybe next week after black Friday week is over.
