Mobile commerce is still unchartered territory for many retailers, but it’s predicted to be worth more than $3 trillion by 2017. 'Tinder for shopping' app Grabble is luring shoppers in with a swipe-based interface that brings a whole new meaning to the term ‘impulse buy’.

Only 0.6% of online shopping is driven by social media, compared to e-mail, which drives 27%. Can Facebook’s Buy button, integrated into newsfeeds, encourage people to spend more when they're on social media? And are retailers really welcome on such a personal platform?

As the smartphone becomes an increasingly useful way to make purchases online, research shows that mobile shopping drives more impulse buys than any other platform. The Europe-wide study found that of 13.5 million mobile shoppers, 42% regularly buy ‘on impulse’ via smartphone.

Natalie Massenet, founder of Net-a-Porter, has been touted as ‘the woman who changed the way we shop’. Now, she’s at it again. In a bid to take a slice of the 36% of online purchases made via mobile, Massenet is launching The Net Set; the world’s first mobile, shoppable social network.
