Like everyone, I will also say ebay is your best pal. Simple organza bag, 100 for about $5. If you buy actual boxes, I found a couple of cute boxes, 20 for $4. Shipping is of course free if it’s coming from China. Ebay and Aliexpress also has actual favor boxes, with like soaps inside or something like that, something to consider if you’re looking for bags strictly for favors and not necessarily candy and stuff.
