I dont't trust Ebay because the dealer might sell fake fish food, but if a dealer has at least 4.5 stars with over 100 reviews, then it's worth the risk. I bought Grand Sumo at petzone SD in San Diego which only cost me $33 included tax. Since I live in Los Angeles, I don't have to pay for shipping, I just going to drive to there for 2 hours to buy fish food. This is there website petzonesd.com
