HSN is getting the holiday gift shopping season under way with a campaign reaching across its TV network, HSN.com, its mobile commerce site and apps, and social networks Facebook and Twitter. Dubbed “More Amazing Gifts, One Amazing Destination,” the marketing campaign will include an interactive online scavenger hunt designed to help customers find the latest in gifts tied to products from several big-name designers and celebrities.

HSN, No. 26 in the Internet Retailer Top 500 Guide, announced its holiday product line-up includes new fashions from Mariah Carey, Iman, Queen Latifah and Twiggy; home products and décor from Nate Berkus, Joy Mangano, Jenny McCarthy, and Vern Yip; and beauty products and tips from Mary J. Blige, Jennifer Flavin-Stallone and Kate Walsh.

Until Dec. 20, shoppers can play HSN’s “Amazing Gift Giveaway $150,000 Instant Win Game and Sweepstakes,” sponsored by Kraft Foods. The weekly game is part of the HSN Arcade on HSN.com.

Players can receive promotional offers ranging from discounts of 10%-15%, $20 gift cards, free shipping and handling, and Kraft Foods holiday offers. Starting Oct. 28, weekly winners will be announced during HSN’s Gift Friday TV shows and will have a chance to win all the gifts featured during the 4 p.m.-5 p.m. hour Eastern time.

Weekly online video “super challenges” will guide players as they hunt for clues to earn additional entries into the grand prize sweepstakes. Grand prize is $12,000 in products and HSN gift cards.

In addition, the Holiday Gift Store, located on HSN.com, provides customers gift options in multiple price ranges, including gifts under $25, under $50, under $100 and luxury gifts.
