Dell sells a variety of electronics on its site for which you could use the gift card.
Brad's Deals Editor David,
Get this Vizio 2.1 Sound Bar System (model SB3821-C6) plus a $50 eGift Card for $149.99 plus free shipping at Dell. This matches the lowest price we found online, but the addition of the gift card, which you can use to buy a variety of electronics and accessories online at Dell, makes this the stronger deal. This system has a wireless subwoofer and has built-in Bluetooth for streaming audio from mobile devices. Note: The gift card is noted in the shopping cart after you add the soundbar and it will arrive separately via e-mail. Sales tax is charged in most states.
