I am a third party seller on amazon. What is happening typically when you see those crazy prices is that many sellers and companies list items on amazon using software that will aggrigate there listing data from another site like google shopping or ebay etc... and feed that info to amazon. Sometimes the data gets mixed up and this is how the pricing gets all screwy. You will see this on google shopping and ebay at times too.
If you have ever clicked on something in google shopping and been taken to a totally different item, this is the same type of corrupted data where the info got mixed up.
