Amazon believes if the shipper just drops off parcel on porch and it disappears it is my problem. I didn't receive my item... I am out money... but not their problem. So for all I know shipper could say it was delivered and walk away with it or a person on the street can walk up and help themselves. At least Canada post puts it between doors or leaves a pick up at outlet card. I am out money and they don't care.
I used to be really happy with Amazon. This has caused me to want to close my account and I spend a good deal on this site
