What is saved
The buyer page can keep up to ten recently reviewed SKU lists on that device for the signed-in customer and company location. It does not store the original uploaded file. The three newest lists appear on the page; View all recent lists opens the searchable history.
Use a saved list as input, then review it again. Prices and availability can change, and a list saved at another company location is not a price quote for the current location.
Switching between Paste list and Upload file should keep the unrefreshed pasted text available. Editing after Review clears the old result and Checkout link. Clearing recent lists removes this device's saved entries for the current location, not Shopify orders or Drafts.
