Thanks so much guys.

I will finish the book in the next couple of days. After that I think I want to visit some head shops and try to buy stuff locally. I am very uncomfortable with leaving a trail by buying stuff online - even if the stuff is legal to buy. You never know who might be watching.

I don't know if aya or mimosa hostilis, etc, are sold in head shops or any kind of shops but I'll have to find out. Ideally I would love to buy everything locally and pay in cash and remain in the shadows.
