Regarding Costco pork belly being in stock, in the Sacramento metropolitan area there are a lot of Costco stores. Some never carried the pork belly, some only some of the time and some all of the time. The common denominator for the stores that carried them all of the time was that they were in neighborhoods that would be considered ethnic. I don't know if Costco in other parts of the country carry items by demographics but it appeared the case in Sacramento.
