If I understand it correctly, what you’re selling is the adjustable mill (model BBA) which lists at $99 with the gear drive option and the case hardened rollers option adds $50 and $30 respectively.
All of the above pricing comes from Schmidling web page:

From them we’d need to pay $15 for shipping so with your offer for free shipping there saving of $9….
If what you’re selling is different let me know.
