I checked with our Vets and they charge $47.00 for the Home Again chip and $12.00 for lifetime registration fee with the company. I wanted to get the Avid chip because that is what Tucker has (from the Shelter). I checked with a new vet that opened offices last year nearer to where we live. He only charges $35.00 for the Avid chip and the registration fee is $15.00, so I made an appointment for Hannah to get hers next week. Yikes...we' shall see.
