Ok, so after saying I had a problem canceling Glossybox and ended up with 3 boxes when I only wanted the one, I signed up again. I couldn't resist the free month of Ivory clasp. I signed up for Glossybox on June 16 it was stated that June would be the first box. I then canceled the sub the message I got when canceling was that July would be my last box. So it seems that their policy has me on the hook for 2 boxes and not the 1 I thought I was signing up for. I think this is shady for sure.
I must remember and not be seduced by tempting deals.
