Well, a lot of my knowledge came from Basenotes off the start. I just read up about a lot of stuff, spent hours a day on the forums, and slowly started buying bottles and samples. I am still pretty new, but I know which notes I like generally, and I have a decent range of fragrances that I have gotten my nose on. I suggest you join other sites and some facebook groups and buy up cheap samples and decant and do it that way. Some places like the perfume shoppe offer 5 samples for $15, which is a good way to get to know even high end, expensive stuff.
