Additional Serial Numbers for existing users
$275 US (+ VAT in the EU). You can order an additional Serial Number at any time but you must have already purchased a First Serial Number.
You can protect an unlimited number of copies of a single product with one Serial Number, including different versions of the same product, but you need an additional Serial Number for each additional product.
For example, you publish two products: SuperDog Version 1.0 - for the owners of kennels - and SuperCat Version 1.0 - for the owners of catteries. If you want to protect both SuperDog and SuperCat with Sheriff you will need to purchase two Serial Numbers; the first Serial Number will cost you $550 and the second $275. So your total outlay on protecting both your products will be $825.
