I keep the prices in sync with Amazon. If the phone is not available from Amazon directly - as is the case for the Nexus 5 - I resort to the list price. I could resort to the lowest price from the Amazon marketplace but I have to check first if that makes sense in all cases.

Where is the list price of a 32gb Nexus 5 $649? The price on Google Play is listed at $399, and has been since the phone was launched over a year ago.
