I have a small business making soap and other essentials like lotion, creams, and such. So I have spent a LOT of time checking bottle suppliers for the best value and price. My go-to company is Specialty Bottle - Glass Bottles, Glass Jars, Tin Containers, Vials, Plastic Bottles, Plastic Jars for Food, Cosmetics, Candles and Aromatherapy. They have just about any size you need, in amber and cobalt blue. Some of the best prices, quick shipping, and good customer service. I've been using them for 8 years and have never received an incorrect order or a broken bottle. The best bit is that there is no minimum order and no handling fees so you can order 1 bottle or 1 case. Just all around good guys. BTW, amber 1/2 oz dripper cap bottle is $0.90 each.
