commision at sales

How much commission does Johnstone Charge? I have heard I.H. charges 10%(you have to be a member) and from what Ive read on the internet most places in u.s. charge around 20%. Some take 10% from seller and buyer both. It sounds like some only charge 5% on livestock. Just looking for information.

MooseJaw is high, I believe it's 30 or 35%. I think it's on their web site.

Yep, it's quite steep. Quoting from their website "Boxed animals 30% on the first $30, 25% on the amount over $30"
