How should everybody pay for their bicycling supplies or anything else? Are cash payments obsolete in the days of bank cards and smartphones? I believe some Car Free People ride bicycles and many have smart phones, some shop at their local grocery stores, some eat their meals at restaurants too, so are the method of payment at those locations and for those products/services also definitely a living car free/light topic because somebody on the LCF list is curious about the topic of payment options?
