GlossyBox has announced the Mystery Throwback Sale. This is a sale of previous boxes. You do not know which one you will get, but thats the fun of it.
Two Boxes - $24
Three Boxes - $30
If you place an order for more than one at the same time, then it guarantees you will get different months. I was having a little issue with the website, sometimes it was working and sometimes it was only showing you could purchase one. I did manage to get the two box option.
