I purchased 5 bags of cereal from www.vitacost.com and paid for all 5. One week passed and I received a notification from them saying that they had only 4 bags left in stock and asked me to contact them as soon as possible. I sent them a message but they did not reply. Then I went to their website, found their phone number and called. Their rep said that they will ship me 4 bags and give me a refund for the fifth bag. Seemed like a great deal and I agreed. I received 4 bags of cereal but they did not keep their promise about my refund. I'm very disappointed with Vitacost.
