Price Sequence Guarantee
The price sequence guarantee is enforced for both synchronous (individual) and asynchronous (bulk or feed) updates. These different methods have different SLAs; there is no guarantee that price updates will be received in any particular order.
The price sequence guarantee ensures that the latest price update, based on its creation timestamp, is the one that changes the price of the item, overwriting the previous version. Price updates received with an earlier timestamp are ignored. As a result, we recommend all feed-based bulk updates base the value of feedDate on UTC.
