I know costco.com can buy cheap minoxildil, but I live in HOng Kong. Do any of you guy know where can I buy cheap propesica and minoxidil 5 %?

For finasteride (Propecia &/or Proscar):

http://www.generics-online-pharmacy.com/ProductList.htm

Costco does sell 5% minox.

jackc:
You can also use www.prescriptionskeywest.com if you want the cheapest non-generic Proscar/Propecia that I've found. I've bought from them twice with absolutely no complaints and fast shipping.
You can also buy minoxidil (generic or Rogaine brand) at www.minoxidilshop.com. I think their prices are quite good and their site has a lot of info. Looks very much on the up and up, but I haven't purchased from them. If you go to www.yahoo.com, then "Shopping" and type in "minoxidil", you'll get plenty of hit and many of the sellers have very good prices and Top Yahoo Customer Service Ratings.
Hope this helps.
