Seat Belt Cert Questions

I have to re-cert my belts this year, just took them out. It's usually around $80 to do so. I have done it in the past and it wasn't much cheaper then new one's. The nice thing is you won't get 6 month old certs. They replace all the belts so they are basically new. Usually a friend and I send them in at the same time, this year there will be 3 of us sending them in. We just split the shipping.
