If there was a package free supermarket would you

[vwagen007]

i.e. one where you brought in your old coffee jars, detergent bottles, egg boxes, washing powder boxes etc etc and had them filled up. It wouldn't sell everything, but most of what you need. If you had no container, it would be supplied in a paper bag, or in a container you could re-use next time. Products would be the same trusted brand names that are sold everywhere else, not cheaper, inferior versions.
Please answer honestly as I'm opening this shop next year, and this is my paper-free, environmentally friendly market research!
