I bought some 5oz woozy bottles with caps on Amazon. The caps they sent are horrible and don't fit the bottles. I think the standard woozy cap size is called 24-414. The threads are poor and they will strip when you try and tighten on the bottle. Anyhow, everywhere I look for caps they are 5-8 cents a piece but lowest shipping is $25. Is this par for the course? I should have used specialty bottle to order bottles and caps. Lesson learned.
