Best Buy Credit Services offers several limited time 0 % interest offers. We have used several of these offers but it seems that, because we tend to carry a non 0 % interest offer as well, no matter how much we apply over our minimum monthly payment, none of the funds pay down the 0 % interest balance so that we eliminate that balance before the expiration date. We then end up paying interest on the accrued interest as it is added to our principal balance. There is nothing on the statement that discloses how to pay down those balances. 
This month we made a significant payment to the card to payoff an existing 0 % interest balance before the expiration but none of the funds were actually applied to that 0 % interest balance. We contacted Best Buy Credit Services to inquire and were told that " No, the information is not on the statement '' and that we would have to contact them to let them know how we wanted to apply any funds over the minimum payment. I feel like this is an unfair practice and, had we been informed of how to pay down that 0 % interest balance, or that there were options for payment plans, we would have saved ourselves money in the excessive interest that we are now paying on those accrued interest balances that applied to the 0 % interest promotions. Best Buy Credit Services needs to revise their disclosures in order to advise customers of their payment options for 0 % interest balances so that those balance are less likely to result in negatively amortizing balances and excessive interest charges.
