Berlin in February is grey, cold, and brilliant. The summer crowds are gone. You can see the art at the Altes Museum without a wall of people in your way. The clubs stay warm regardless of the weather, and the lines are shorter when it is freezing outside.
A trip like this costs about $2,100 for a week. You can manage that by breaking it into monthly payments of $140. The Discover it® Cash Back has a 0% intro APR for 15 months on purchases and balance transfers to help with that.
This is not a gift. The 0% intro APR for 15 months on purchases and balance transfers is a hard deadline. If you still have a balance after 15 months, the standard interest rate will apply to whatever you still owe.
