I think better way is:
1. make some money (if u r lucky ull drop BE sell it for 250k)
2. go to hefei and buy some HP clothes(female) +200HP for 100-150k(upper)
then make a stand and sell it for 200k ull see what prices r good and which r bad...
if u dont have a time to play only to make money this is the best way... buying cheap and then selling it for higher price...
it really works...
made about 2M that way

on RC1 i got +200HP (upper) +15HP(lower) + 100 dmg gloves and more
hint:
BE u can sell for 250k without problems...
ginesng is now for 100k so odnt care about price list on official forum...
CHi kung and dmg pills r unsellable(never sold any CHi kung +800 even for 200k)
HP clothes upper 200HP(200k) 150HP (150k)
lower 150HP (150k) 100HP (100k)
manuals...unless they r II - IV u cant sell em(better sell em to vendor)
normal weps see price at vendor than +10k...
blue weps if they dont have special bonus (heavenly and so on) u can sell em for vendor price + 20-30k...
Tomes - if u have lightfoot from Demon or Wu tang u can sell em for 100k the others are very cheap because u drop a bunch of em...
ANd speciality of this game is that there is many people who sometimes miss some "0" in a price so u can buy stuff cheaper...
