Do you think it would be useful for me to contact the manufacturers for the UPC codes? For instance if I do decide to narrow down the "Taylor-made Drivers category into say 6 Taylor-made drivers. Would I get better results at that very narrow category using the UPC code only? In your experience do all the datafeeds from all the retailers include UPC's in them? It would be nice to have JUST the one product come up and not have some random stuff show up where manufactures keyword stuffed the tags and such. I have one retailer I can't use because in his tags for say "Taylormade R11 Driver" it will say Taylormade, Nike, Mizuno, Wilson, Ping, etc... ) I guess they figure they want the club to be included in searches for any driver, but makes the datafeed very hard to use. So I don't!
