I've purchase hundreds of items from Amazon.ca. Their retailing practice, return policy, etc. is excellent. However, their delivery guys have made so many mistakes since the beginning it's not even funny - parcels were dropped off at the wrong address, called somebody else's telephone number and left the parcel with the wrong person; etc. Yesterday they dropped off my package, while the concierge was unavailable, with a label taped over my name and address. My concierge had to very carefully peeled it off to find out who the recipient was. I know delivery staff don't need high intelligence for their job, but this is definitely not acceptable from a human being.
