I can't seem to find in the import mapping the Price A [@store_price@] when bulk importing from .csv
Has anyone had this issue? Using Price A to map to doesn't map to [@store_price@]
The interface is a bit misleading here. You can't actually import to [@store_price@], it is a calculated field used for displaying the right price on the website front-end.
Try [@price_1@], [@price_2@] etc for the per-user-group price.
Also make sure you're importing to the child product's SKU when working with variations.
