I 'accidently' signed up for Amazon Prime. Mainly because I was greedy and wanted my package to arrive sooner. It said it was a FREE TRIAL of Amazon Prime, so I gave in. I was using an Amex gift card with just over $19 left on it out of the $100 it originally had. The total cost of my purchase was just over $15 and I chose NEXT DAY AIR as my shipping service. (Always wanted to try NDA) Then I get an email saying that my package has shipped and as of 10:15PM Saturday, it is in Philadelphia and in transit. But I got another email saying that Amazon has DECLINED THE USE OF MY CHOSEN CREDIT CARD for Amazon Prime. The reason being is that because even though I signed up for a free trial, I will still be billed $80 (or something close to that) once the free trial time has expired, which I was unaware of. I can't cancel the order and I can't cancel the free trial! I'm stuck! At least I got free shipping.
