Okay I'm going to attempt to explain what I mean here but this may get confusing. How many times per month or year or week to you need to use a bag in order to justifying your using it enough to keep and not sell? KWIM?? I was thinking about this over the weekend and I would say that if I used a bag at least 5 times per year for a span of at least 1 week at a time (meaning I could not use it for one day five times) I would keep the bag. How about you??
