If I come back in 24 hours, same thing happens.
However, no problema at OM/OD.
Basically shut this card down at the mall.
Citi is known to do this if you are new to them and "trying to learn your spending habits". I had this issue when I just got my Citi thank you premier card. If you call ahead of time to let them know of a large purchase is coming up it should go through or try to slowly get into that kind of spending habit.
