How long should a bull be guaranteed?

[CR]

Ala- You might want to consider a return policy in the future. I bought a 878 son a few yrs ago and he had feet problems. I had him trimmed twice, but got tired of that and decided to send him to the sale. The group where I bought him had a policy that they would give the purchase price back the first yr on the purchase of a new bull, but that dropped 10% per yr after the first yr. I thought I would get more for him at the sale and did.
