Honestly, I am wondering whether the copy of yours is a
photocopied, manuscripted or an original.
If you are photocopying from the original guide in National
Library, you will be INFRINGING COPYRIGHTS. You will be sued for
selling such copies.
If you have a manuscripted copy and want to sell them, I CAN EVEN
GIVE OTHERS FOR FREE. Sharing is always better than selling for
personal interests.
If the original copy is really yours, I have nothing to say... BUT
IF YOU ever ever steal it from the National Library, you will be
PROSECUTED.
Anyway, the way you are selling and the price is totally
UNREASONABLE. What makes you think it costs $100? And for your
information, I have seen some stalls in the flea market selling
some 1980 old guides for ONLY $10. So what makes you think your
guides are worth so much?
Anyway this thread is only for your personal interests in bid of
making profits. Take note: this is not a marketplace. It's a place
for forumites to share...
