The sad fact is that you’re not entitled to a refund from Amazon for a post-purchase price difference. There’s no wiggle room about that, officially. There is some hope, however, because you’re a valued customer and Amazon wants to keep your business.

In economics, the assumption of ceteris paribus, a Latin phrase meaning “with other things the same” or “other things being equal or held constant,” is important in determining causation. It helps isolate multiple independent variables affecting a dependent variable.

Well, the good news is Amazon will refund you the difference—if you ask within the right timeframe. If the price drops within 7 days of the delivery date on an item that was shipped and sold by Amazon, just contact Amazon and they’ll refund you the price difference. So now you can shop a little more confidently.

Click Match price in the Lowest Price + Shipping column of the listing you want to change. Alternatively you can click the Match low price button for the listing. The item price in the Price + Shipping column will update to match the total price in the Lowest Price + Shipping column.
