I recently started shipping my jewelry in cardboard jewelry boxes and now I'm looking for the cheapest place to get them. I've been getting them at Michael's, but they come out to about $0.50 each that way. I'd like to keep my costs down and I'm sure there's a much cheaper place to get them, but most of the ones I've found online still end up being $0.45-.48 each once you factor in shipping. Is there a cheaper place to get them (preferably without having to buy 500 or so)?
