Hello,
I hope this is OK to share here... I've seen others sharing ThredUp codes, this is similar.
Schoola is an online thrift store & 40% of their profits go to public schools in need. I'm a public school teacher so I suppose I'm biased towards this site!
If you use my link YOU will get $20 to spend and I will get $20 to spend. They also give you $5 to spend when you request a bag (to fill up with your own clothing you want to sell).
