My hunger is kinda moaning at me again

I'm still working through RRTCM and Street Magic (PZ) but I'm looking to find something that teaches some more advanced effects and sleights. I'm probably trying to run before I can walk but....I just can't help it really

I've been on NUMS and looked at the Card College but firstly its a little pricey for me and the first 2 volumes seem to be repeating what's in royal road and street magic. What really interests me is what I've read that is in Volume 3 and Volume 4.
Does anyone know other books that provide information on what is in those volumes?
