I paid for Jan & Feb & verified I got 5% and I think I am going to prepay a number of months in advance because the 5% cashback exceeds even the best CD rates.
Really, a case could be made for prepaying an entire 9 months worth. I have been doing this for far less with my Power Bill and I only get 2% back and it costs a small fee. That 2% card currently has a deal where if I spend over $350, I will get an extra 1% up to $20. So now might be the time to prepay my water & power bills too. That deal ends April 30th.
