The only "installment plans" that you can do with Best Buy is to get their Best Buy credit card. For the credit card there are two options... the first is the Best Buy credit card that only works in Best Buy. The second is a full-blown VISA Best Buy credit card that can work anywhere VISA is accepted. Both credit cards have some good payment options like you can choose to get 5-10% back in points or you can choose 6-12 months no interest. So if you have the cash flow and can pay off the laptop in 12 months, you're golden and don't have to pay one cent in interest.
