I have a good relationship with the owner/employee's at Mutt's and Butts. Sometimes they have good stuff/deals, sometimes not. I'm patient and check to see what they are getting in periodically since they're local.
I haven't checked out many of the suffolk places. Only one I visited was PetsWarehouse. I was impressed with the clams they had, but not much else. Could have been bad timing on my part.
Local reefers are usually the best route. I've gotten some great stuff from people I've met through RC.
