I've tried using both /catalog/v0/items/ and /catalog/2022-04-01/items/ getCatalogItem request to get the list price of an amazon item, and both return either the incorrect price, or none at all.

This issue specifically focuses and has examples for /catalog/v0/items/

SP-API Name and Version or Report/Feed Type

/catalog/v0/items/

Expected Behavior

I should receive an API request with a correct ListPrice attribute.

I am receiving an incorrect ListPrice.

Current Behavior

The list price I receive from the API request is not the correct displayed ListPrice on Amazon.

There are no direct Errors other than an incorrect ListPrice.

The specific marketplace I'm using is ID: ATVPDKIKX0DER (USA)

If this could be changed to receive the correct ListPrice as displayed on amazon.com, that would be awesome!

Context/Screenshots

API Code:

@sp_endpoint('/catalog/v0/items/{}')
def get_item(self, asin: str, **kwargs) -> ApiResponse:
    return self._request(fill_query_params(kwargs.pop('path'), asin), params=kwargs)

Example code:

asin = 'B0157FD02C'
data = Catalog(credentials=CLIENT_CONFIG).get_item(asin,MarketplaceId='ATVPDKIKX0DER')

Resulting API Response:
