I am trying to buy the Shadowfell Expansion through the DDO Market. When you add it to your cart there are three special offers, one is to purchase 11,000 store points normally 99.99 for 59.99 however when I click add, nothing happens. I also wanted to purchase the Underdark Expansion and saw there was a special offer for that, if I hit add it works. Is the point offer still available?
