Well I have the 2 grocery side bags, my backpack and my wife has a basket, between all that we can easily carry home enough groceries for the 2 of us for a week. The great thing about using the bikes is that it really does cut down on impulse buying but we don't have to meticulously plan on what we need to buy either. The side bags are great, they can fit a paper grocery bag or can just fit a case of beer
