I’d guess it isn’t… i recall that the individual price for one of them was a bit above 60$, so the compound price should be around this
Edit: I was wrong, i’m sorry 
The 60 were for another order, just checked
The Six Healing Sounds was the one i was recalling
Most expensive was audio for the Throat chakra, $35. The rest of them were 20 or $22. If I remember correctly.
Found it:
I remember checking the shop back in the day and it seems mandelbrot was around $80~100? Not sure if I remember correctly though.
Sooo much to keep up with
