I bet there are sites like this already but I can't find one to give as an example. What I want is to search through for example a bunch of classifieds-sites with one search. So I type in for example "used Volvo" and I want my script to search through all the biggest classifieds-sites and display the search results on my page. Please give me all info you have on this. Is there a script like this, is there one free, is it legal to do like this, any other tips? Thanks in advance.
Learn to code? Other option is figure out which classifieds you want to pull from and hire somebody to pull the results to a local db. Then display. Odds are that will be expensive too. Totally skips the legality of said enterprise.
