If you are a large purchaser, you can almost always get a better deal opting out than letting the class lawyers represent you. With your own attorneys, you can negotiate cheaper fees and more creative settlement arrangements, like discounts on future purchases, etc. There's some risk to opting out and it requires more active involvement, but smart law departments can really contribute to the bottom line instead of being a cost center.
