Yup I do rescue plants too sometimes, it is a good learning process for me. Sometimes they make it, sometimes they don't. But I choose the plants I take, since I do not have a lot of space.
Succulents are really easy to rescue. I try to get my rescues if possible in late Fall. Not so much into winter already, it will just be too much of a shock for the plant during transport, and more frustrating, since most of the plants are on slow down mode already, or more often too dead to revive.
