I'd say it's def. worth it. They offer a lot more benifits than other registries. They'll send you the certificate of registration and a family profile disc. On the family profile disc, you'll be able to click on any dog that you've registered through them and see the dogs pedigree along with any pics. We have links on our page leading to our dogs pedigrees if you want to check it out.
By being a member you're also able to submit as many pics as you want, post ads, etc.
On the dashboard by your profile picture are tabs, and if you check out 'upgrade' you'll see the benifits that you'll receive once you register through them. APBR is awesome, enough said lol.
