I saved the current prices on my listings by going to my Manage Active Listings page and saving it as a complete page for each page, also printed it to PDF as well as a backup.
This will make it easier to reinstate those prices if Simple Delivery was imposed then later removed, and it could be useful to list items on alternative platforms.
Otherwise that information could be lost, so backing it up could be a helpful tip to avoid a lot of extra effort to recreate it in the event it was needed. Of course it wouldn't apply to everyone and depends on what you were selling and if you already kept records of this.
