before my company sets up an ecommerce site to sell gold and silver direct, we need to ensure the ecomnerce software can dynamiclly change the product prices every 5 minutes according to the changing spot prices of gold and silver limked from ay 3rdwebsite.
We will design an develop the site.
We require custom api programming to acheive the dynamically changing prices of our products. We are willing to work with any ecommerce software.
i've just done something similar for a book store using x-cart. The field updated was the item available(stock) but updating price won't be a problem at all.
