Going to down to one car in my household. I won't be commuting to work at all. Just need a bike to go to the store and random appointments around town. Before I she'll out $180 for panniers, is there an easier cheaper way?. My bike has a rear rack but maybe I can just get some kind of baskets? Panniers look better for sure but if I could find baskets that are easy to take off that might be a solution.

Most I'd need to carry would be groceries for a family of three of 5-7 days
