And btw this is like the most I've ever spent on a collection before. Lol my poor wallet.
I agree with darkpearl, you can easily skip the quad and save your money. Firstly, quad shadows are often of crap quality (they like to package them with lousy ass powdery zero pay-off shades) and secondly, the colours are nothing special in themselves from this particular collection. I am very sure that you can find equivalent colours from the permanent range. I think the last good quad that I came across from MAC was Bare My Soul from Temperature Rising, but I can tell you, in the 8 years that I've been using MAC, I've bought 3 quads and kept only one (Bare My Soul).
