Well, like I said, I believe this is the first time I've had any trouble with Amazon (.ca). That said, apparently you all have had or are having a similar (or worse!) experience with them.
Then again, we're talking about at least three different companies here, as far as I am aware:
Amazon.ca (Canada)
Amazon.com (USA)
Amazon.co.uk (UK)
These are separate entities, right? Maybe the problem is farther up the distribution food-chain, so to speak. Has anybody had similar trouble with other online retailers?
