Hi Jamie,
Thanks for asking.
It is slowly growing, word is getting out on social media and there has been a couple of offers that have taken off this week (one was a pair of womens boots that seemed to get shared a lot and sold 20 pairs through the site, the other was a frozen doll).
Have run a competition for signups so just need to start getting people more active at the minute, there are a fair few people coming on to buy / compare price but don't sign up to get cashback so have been tweaking the site to get them to convert into members.
