A:Answer Best Buy offers financing via their Best Buy credit cards, so you'll have to apply and be approved for one which you can do in store or online. If you already have one, then you'll need enough credit available on the card to make your purchase for a given offer. For instance, if the offer is for any purchases $499 and up and you wish to purchase an item priced at $499, you'll need $499 + tax in available credit to receive the offer. You'll have to make minimum payments and most offers have deferred interest based on the term length: 6 months, 18 months, etc. If you skip a minimum payment or do not pay off the full amount by terms end, the deferred interest is applied and you'll have to pay it.
