I have an online shop selling computer staff. Till now, I manually import products, or change prices and descriptions. But it is very difficult to watch all price changes so I need to automate importing products and recalculating prices, exchange rates and availability of products, from supplier's data file. I can import from xls, csv, or similar, but I would like an automation to recalculate availability of products, prices, in a way fast and familiar. Also I wish I could import descriptions directly from supplier's website to interspire product description, photos and keywords as well.
