New accounts get $10 credit
Here's the main link. http://www.liketwice.com/ no referrals, just want to share the freedom!
If you download and sign into their app (LikeTwice) on your iPhone or iPad, you get another $10. (sorry, I think it is Apple products only).
There is also a 25% off code if you complete a video/survey: https://www.liketwice.com/buyer-quiz/ 
So, $10 new sign up + $10 download/sign into app + 25% off code = 1-2 pieces of clothing free. Yes, you can use it towards the $5 shipping.
I've never had to put in my Credit card number at all. The survey and videos are a bit boring but hey, if you want that extra percentage off, why not? Completely free...
