a strange phenomenon

[pda321]

guys, i'm wondering why, when the prices of the bulk powders--while divergent--are so negligible vis-a-vis the final sale price of the particular steroid, something like anavar sells by multiples more than winnie? is this a temporary artificat of the pre-china-direct era that will resolve itself over time? or is there a reason here i'm missing...it seems to me they should be priced a lot closer...
