I like the smaller St Christopher's shop on Lordship Lane and the staff are always friendly. The big one's not too bad either. Jennys is right about the new charity shop at Camberwell, alongside from McDonalds, is in aid of the homeless charity Crisis. I've donated some bits over the weeks and the staff are always friendly. The phone shop at Camberwell closed a month or so ago. Walked past the other day and that's going to be another charity shop (Trinity Hospice).
