I've been buying my bottles from Specialy Bottle company too, and can say they are an excellent source. There's no minimum buy required - you can buy only one bottle if you wish.specialty bottle in seattle-

no minimums, .60 per bottle with caps, don't need the dropper insert if your sauce is the least bit thick, and if you send me a bottle of your sauce...I'll send you some black shrink bands!
