Removing products that have been deleted in your store
When products have been deleted from your shopping cart, they are not automatically deleted from Spark Shipping.
Products MUST be deleted from your store first and then can be purged in Spark Shipping. This process is run on a vendor level.
How it works: The purge process will check every SKU mapped to a vendor against that SKU's existence in your store. If Spark Shipping finds that the product still exists in the store, it will keep it. If it finds that the product has been deleted from the store, it will also be removed on our end.
How to: If you wish to remove products from Spark Shipping that have been deleted from your shopping cart, go to your vendor page in Spark Shipping:
Vendor > Maintenance > Purge Deleted Products
