WTf????

So I work in an acting school and I order all of the stationery supplies for the school. Well today I get an email from one of my suppliers saying if I order from them they will give me all 3 Fifty Shades books......? WHY?
Firstly is that not sexist? Are they supposing that all the buyers of stationery are women?
Secondly, what happens if someone is unhappy with the content of these books?
Seriously - that is not an appropiate "offer" to entice people to buy your stock?????

I have read all 3 novels but I still don't feel this is a suitable offer to give to businesses...

What do you guys think?
