Deal-seeking shoppers often pass along information about new card offerings on social media sites such as Twitter and Facebook, says Testa.
You don't even have to be anyone's "friend" to learn about a special. A search for "discount gift cards" on Twitter yields several results from various users who simply want to share information on deals.
Testa urges caution, however. While it's possible to find out about several deals from people you don't know, buyers should only purchase the gift cards from reputable sources, he says. The offer could potentially be a fraud. "It is always buyer beware," says Testa.
