Price Tapestry
Price Tapestry is a great program for importing any kind of merchant data feed into your site.
In our testing it took about 5 minutes to setup. We then uploaded an XML feed containing more than 600 products from a 3rd party merchant into the feeds directory of Price Tapestry. Within a few minutes we had all the product fields mapped out and imported into our database.
This is a great program written in PHP and we highly recommend it for anyone building a shopping related website!
