Is buying green in bulk an oxymoron? We're torn. Marketing principles (not to mention American waistlines) hold that selling larger quantities of consumable goods, such as food or beer, leads to increased consumption. But this is not so with goods that can be inventoried, such as paper towels, vacuum cleaner bags, and cleaning solution: you're not likely to use more if you buy more -- you'll just buy them less often. That's good news for Costco and bad news for your corner store.
So we're thinking of doing a green tour of sorts of Costco, pointing out the green and the not-so-green products available in that particular retail nirvana. What do you think? Is there anything in particular we should seek out?
