#=======================================================================================
# The problem
# So many times we want to keep checking price of particular product on a certain website
# like amazon so as to get the cheapest price possible but are busy to continuosly do so 
# This script is exactly going to automate that and send a mail when price falls below a
# certain threshold setup by us
#====================================================================================
