Because it's all in one place, it's got all the things id usually buy from local shop. Spreads the cost which means I can get it all in one hit and not only be able to purchase when you have the money. They also allow you to choose the day that you want it shipping meaning that you choose when to pay. Which is good if you haven't got the money there and then. Only problem I have had with flava is obtaining a refund after I cancelled my subscription before the trail was over they took the money but refunded it but it takes 31 days for it to get back to you. Apart from that it's great.
