I totally agree with you Coppit. I got trapped once, even though I didn't complete my purchase, when I realised I was in Prime. I emailed and requested my subscription be cancelled immediately (with added moan) and received an email apologising and saying the subscription was cancelled. I still checked at the end of the 30day period, but no charge was made. However, now I very rarely use Amazon and do most of my purchases through EBay, which I find has good prices and good service.
