I usually order 4 pair at a time, and I've bought dozens over the years. They have gotten a little more expensive, and I suspect that may be due to the fancy packaging, which I throw away. You should consider offering bulk packaging to cut down on the cost and the waste.
They used to come in plastic bags, which was fine. I don't need the fancy boxes, or the cloth bags. Wrap them up in a decent microfiber cloth and ship me 4 at a time.
