I also have a listing for 10 bags in the same color. This is a new item for me, but I do have an excellent source and if you need more, say 75 or 100, or however many you'd like, I can obtain them very quickly, and I'm always happy to do custom orders! Maybe you would prefer a mix of colors, or a different size -- no problem, just convo me and I'll do the rest.
If my shipping cost is high, I will refund the difference. I never charge for handling or packaging materials.
