Since I got my bike last summer, the great majority of my shopping trips have been on it. The savings I've made by not needing to use a taxi one way - too far for me to walk from the bus while carrying shopping - have already paid for a big chunk of the cost of the bike. I'm currently awaiting the arrival of a rear basket so I can carry even more. I already have a front 'Kanga rack' on a frame-mounted luggage truss, which doesn't impede the folding ability, a pair of panniers and a front handlebar basket for anything lightweight that doesn't warrant the Kanga rack.
