1) ask what is the interest on the loan. If you miss a payment can they raise the interest rate.Sometimes they will lower the interest rate if you put a big down payment.on the item or you have good credit.
2) It would be a good idea to put purchase on a Best Buy credit card and in some instances if you don't have one and open up an account you may get cash off your first purchase.
