The Teaching Company "Great Courses" DVD's
I recently purchased a DVD from this company. For those not familiar with them, they offer educational DVD's on a myriad of topics including science, religion, history, art etc.
I am very satisfied with my purchase BUT: one purchase and it's like donating to a charity. Every day I get one - or even two - emails pushing yet another DVD series that I should buy. On top of that, approximately once a week I get a hard-copy small catalog in the mail. And, of course, they are on sale for 2 days only!
Like I said, I am happy with my original purchase. But this nagging is unreal.
