When I was looking for grocery style bags for my bike, I came very close to buying the
Arkel bags. They cost more than the MEC bags but are a lot nicer. In the end I decided not to buy the bags but bought the Burley Travoy trailer with the optional shopping bags. I can wheel the trailer into the store like a shopping buggy which is an added bonus. Certainly cost more than the bags but was more versatile for me. Though I like Seattle Forest's idea of the clips and plastic shopping bags, that is a cost effective solution.
