I use this stuff practically every day and wish I could find it in a local store.
Where can I find these glass bottles that you can decant it into?
I would try visiting your local Goodwill and thrift stores. If there's one thing they have in abundance is glassware! I typically find Avon bottles with various amounts of juice still in them, and usually see one or two interesting bottles along the way. Usually cheap!
But honestly, I'm defaulting more and more to the Avon "book" bottles. Hold 6 ounces, thin and compact, they take up a whole lot less space than their car bottles do!
