I think that is nuts! there have been a few months where I might spend 3-4K at Coach, but it's certainly not every month, maybe 2-3x per year. Now I'm all nervous!

Don't worry! It's usually frequent customers who buy multiples of one thing, cheap cheap accessories or just ridiculous amounts of stuff. So unless you are suspicious or weird about it, you have no worries.
