Random tip for social workers

I am a mature student currently studying social work. My random tip to new students is that Vinted is a great source of second-hand textbooks! Last year I had a wardrobe clearout, and had a healthy balance on Vinted which I hadn't got around to transferring to my bank account. I have used most of it on social work textbooks! Obviously the library of the university I am studying has everything online, but sometimes I prefer a physical copy.
