Promoting Amazon through PPC

[Clanouper]

hey guys....
iv'e wanted to ask:
do you promote amazon products through ppc and if so, can you make
profits with amazon in ppc? (i know amazon won't let you promote them with ppc directly so i'm promoting amazon through my site wich is promoted with ppc). the problem is amazons commissions are very low and ppc costs alot of money so i wonder if one can make money that way...
