$25 is a good price. We use AVID at work, and we charge $41 for the chip and implant. Registration through AVID is I think $18 give or take, but it's lifelong. So $25 for the chip AND registration is very cheap. Both my dogs have AVID chips. The one thing you need to be really careful of is that all the information is legible on the registration paper. If anything is off, it'll be wrong when they put it in the computer, and then they won't change it unless you pay the change of information fee. So if possible, type it. You may even be able to do it online by now.
