The site is terrible and difficult to navigate, I looked through clearance until I got bored, a few links:
Women's
$5 slim jeans
$5 straight leg jeans
$5 hoodies
$10 PU jackets
$10 merino sweatshirts
Men's
$5 shorts
$10 jumper
$11.95 flannel shirt with hood
$11.95 flannel shirt
I managed to use the HAPPYBIRTHDAY20 code for $20 off of the clearance items as well (no luck with WELCOME20)
HAPPYBIRTHDAY20 and WELCOME20 didn't work for me sadly.
