the difference is the future, this site with its traffic can crush any online retailer in the pool & billiard world if their margins are right, AZB needs to shift into higher volume and lower GM-that would the most profitable scenario. The sources might need to find religion and cut their prices as well and should to be on this board. I'd play it like that, bigger is better less is more ask WalMart how that worked out.
AFAIK, if you buy through the marketplace you are directly supporting AZ as I am presuming AZ gets a kickback from Seybert's for the referral. I think if you are an AZer and you buy from Seybert's then going to Seybert's through the AZ marketplace will help support AZ and help pay for this awesome new site
