I'm 100% sure you can cancel whatever you accidentally ordered on Amazon.com.
Amazon, in my experience, are very good with returns & customer service.
However, for the record of other readers, if you're in the EU, then you are legally entitled to a refund on anything you buy online within 7 days, even if you buy it non-accidentally and you've just changed your mind.
