Amazon offers an "A-Z" insurance policy whereby they will refund your purchase after investigating the issue, if your purchase did not arrive by the date the originally gave you. However, you have to wait 3 business days before submitting your claim. My purchase arrived during that 3-day period, so Amazon told me that my item arrived during the "wait period," and I'm not eligible for the refund. Sounds to me like Amazon gambles on the purchase arriving during that period and people cooling off. Amazon needs to either change to a 24-day wait time (from its current 21-day wait), or else honor the terms of its refund policy. The customer service people were rude to me, and I don't want to shop at Amazon anymore, after purchasing 4 years' worth of college textbooks and several other books there.
