Those don't come in "books". They are only given for customer service-related issues. I recently got *6* when my wife and I were downgraded from our confirmed, miles-paid upgrades on one segment of a two-segment leg. So we still had the miles deducted, even though we sat in coach for 2/3 of the total trip. So I talked her into 3 segment upgrades each. It wasn't hard, I probably could have gotten 10. She just typed in the number and printed them off.
