It's not direct competition because the time that it is available at the outlets is months after its initial release.
They don't want to make it easy to get the discounted FP bags, that's why you can't order by phone - simple. If they can do phone orders in the FP store they can do them at the outlet. There is no logical reason behind this other than they don't want to.
Yes, it may be months after the release but we have seen bags at the outlet marked down when they are still selling at FP and I am not just talking about the random returns. You are right, they don't do it because they don't want to.
