Since such website make their money from their clients (referrals and such) they are unlikely to see other sites using their data and getting money out of it.
Moreover, this is very local, and you don't mention your country. You wouldn't be interested in a deal with the leading Dutch comparison site kieskeurig.nl, would you?
I want to develop a deals website, similar to http://www.slickdeals.net,
Few thing i have already finalized: - Development environment - wordpress for front end, myBB for community development. - Language: PHP
The points that i am missing: - Database/Data Feed for Price comparsion - Database/Data feed for best deals
Which Shopping web sites are providing product price and best deals via API?
any small help would be highly appreciated.
