I am in the early stages of developing a site. A feature I hope to include is prices from other sites. I am just wondering whether this is going to be feasable as I am going to need keep up to date prices on about 150 products from 10 different sites. I don't know if this possible but is there a way to automatically publish a price from another site, so when they change their price, the change will also take place on my site.

Thanks alot
