Hi Dan,
On a product listing on Amazon multiple merchants can offer the product for different prices. Amazon then chooses the “best” offer among those to display on the product page, in the so called Buy Box.

Keepa does not track the buy box, it tracks the cheapest price of all available offers, shipping costs not included, per condition.

The "new" price type is the lowest New price by a 3rd party seller or Amazon, shipping not included.

When on the product page there is a box on the right showing “Other Sellers on Amazon”, which also contains a link to see all offers. There you should find the offer for $140, shipping not included.

If you want to see a price history with shipping costs included you can enable the price types with a small shipping truck icon next to them. To enable additional price types just click on them in the legend next to the graph. Note though, that we do not track all price types for all products.

If you have any more questions, do not hesitate to contact us at [email protected] or visit our forums: https://discuss.keepa.com

We would much appreciate if you could reconsider your review.
