Data Science Specialization : USD 290 or USD 441?

I am interested in signing up “Data Science Specialization” full course (9 course, capstone project and certificate) and i will “pay per course”.  In the beginning (even till 25th Jan) I saw the entire course fee was USD 290 ie., USD 29 per course. I paid for the first course The Data Scientist’s Toolbox and cleared it. But suddenly I saw the course fees is showing as USD 441. Why there is a sudden hike in price and can it be reduced?
