i dunno man, while revenues are indeed increasing, it seems to me that it is hitting a plateau. interpret this your own way.
total is $239,474 with an average of $39,912 per month. assuming this trend continues that would yield $478,948 per year.
in total BZCN would yield about $2M per year for its whole operation (store + ebay). only delmar knows what the profit is though. remember these are just revenues.
