Good question! Unfortunately, when it comes to ISBN prices, there isn't a lot of conversation about it. The main reason for this is that the price of ISBNs are largely regulated by the International ISBN Agency and their associates. As an essential part of the publishing industry, the prices are not something that will likely be reduced or negotiated on.
That being said, there are ways to save money on ISBNs. Some of these include purchasing ISBNs in bulk, sharing ISBNs with other authors in your network, or becoming a member of a larger publisher who can provide you with ISBNs in exchange.
Aside from that, there are also other things that authors can do to save money on their ISBNs. For instance, they could look into free ISBN services, or explore the possibility of getting ISBNs from a less expensive vendor. A few options include Ingram Spark and BookBaby. It's always a good idea to do your research on any of the vendors you might be considering.
At the end of the day, the price of ISBNs won't be changing any time soon; however, if you're willing to put in a bit of work, it might be possible for you to get some discounts or other cost-saving options when it comes to buying ISBNs.
