Price Scraper?

I need something that will allow me to scrape prices for a product from a few sources -- and then display it in a comparison chart on my website with buy it now affiliate links. I can output the table using PHP but I'm not that advanced at PHP to build a crawler to scrape the prices and then output them.

Is there perhaps a script or plugin already available for this that can be integrated with WordPress?

Generally when it comes to a project like this, you would need to build a separate scraper for each source. You're not going to find an out-of-the-box solution...

I think it will be better if you can get a custom one built for you. That would help you as each source will be unique.

I can possibly build one for you for the cheap, PM me if interested

Just google for price search engine APIs.
