I've made around £1000 from selling stuff on vinted. I sold my old clothes, baby's old things and husbands. It was a really good clear out.
Are you doing shared leave? I don’t know whether it can be backdated but you’d be able to be paid in full for May half term if not. Other than that there’s a company called Hark that does market research for teachers, I’ve done a few and you get between £50-£80 per project.
My only thing I do is selling stuff on Vinted to fund coffee dates !
