You can use the gift card to purchase better audio to go with your TV.
Brad's Deals Editor David,
Get this Samsung 55" Curved 4K Ultra HD Smart TV (model UN55MU6500F) plus a $250 gift card for $799.99 and free shipping at Dell. This matches the lowest price online, but the addition of the gift card makes this the better deal (read more about it here). This curved display supports resolutions up to 4K Ultra HD resolution and has built-in WiFi for streaming content. Note: The gift card is noted in the shopping cart after you add the TV and it will arrive separately via e-mail. Sales tax is charged in most states.
