3.0.0 Migration Guide
Price Checker 2 version 3.0.0 will for the first time use the new Amazon Selling Partner API.
Due to significant differences between the old MWS API and the new SP-API, here are some highlights of changes:
Speed considerations
The basic lookup speed remains at 5 products per second (~~18000/hour).
Search is faster than before for most users (5 queries per second instead of previously 1 query per 5 seconds).
Offer data no longer requires historical data, which makes it faster, however, accessing N different conditions (New, Used, etc) will impact throughput. This is because offers for each condition need to be queried separately leading to a Nx reduction in speed. (Used+New = half speed). There will be a new settings page to control this aspect.
Speed is set per user. This means that you may exceed these guideline speeds
Fees
Fees are provided directly by the Amazon API, which means that they will be and remain accurate at all times.
However, some inferred data points such as “Max cost to 0” or “AMZ price to BE” may no longer be 100% precise depending on the category, and changing the reference offer in Excel (post-run) may not provide cent-accuracy either.
Historical Data no longer required
The following data points will no longer require historical data:
Amazon EAN |

Amazon UPC |

Amazon Sells At |
|
Amazon is a seller |

BuyBox Seller |
|
BuyBox Seller Type | AM only shows for Amazon, not for Warehouse deals. Use historical data or enable Used Offer retrieval to catch cases where Amazon Warehouse is selling, but Amazon is not. e.g. Amazon.com B07GJBBGHG - Warehouse Seller ID is |

AZ Feature #N |
Changes to individual columns
BuyBox Price Used | PC2 will only retrieve new offers by default. |
AZ Feature #N | Renamed AZ Bullet Point #N (e.g. AZ Bullet Point 1) |
Other changes
Keyword searches with up to 1000 results no longer require the browser (Explore automatic translation from website to API, to reduce browser usage!)
Version Specific Notes
3.0.0 alpha 06/05/2022 | Additional Attributes (column IDs 2000-2066) may not return a value. Item lookup speed allowance is shared across all marketplaces, so they can’t run in parallel at this time. |
