Los Angeles-based start up Spreeify.com has launched a ‘one-of-a-kind’ social shopping site hinging on free giveaways and offers.

Users are invited to sign in and take advantage of a variety of deals on clothing, accessories, home decor and gadgets, earning themselves entries into ‘sprees’ – giveaways – in the process.

But shoppers needn’t part with any physical cash to enter the giveaways; entries can be earned by sharing items from the site on social networks. Pin an item, share an item via email, Facebook or Twitter, or simply follow the brand’s accounts to earn an entry into one of Spreeify’s giveaways, which are said to total $1m currently.

There are decent prizes on offer, too. Think Tag Heuer watches, iPad Minis and Ray-Ban Rare Prints sunglasses, not cheap makeup or tacky clothing.

“Thanks to social media, product giveaway campaigns have become one of the most viral forms of marketing for merchants,” says company CEO, Ruben Dua. “What Spreeify does is put all the greatest giveaways in one place to make a real shopping spree-like experience for our members.”

It would be easy to be cynical about a business model that operates on a kind of consumer blackmail (‘share our stuff and we might reward you’) and indeed it will be interesting to see what kind of take up the company – which was only founded late last year –gets.

However, in the few short months the company has been operating it’s already brought in over 300 partners, including Apple, Amazon, Guess, Puma and Swarovski – not the kind of brands to lend their names to cowboy start ups. So, watch this space.
