I found a place locally that sells amber PET bottles, as well as glass ones - it is a wine/beer make your own place.
I mentioned it to my husband, who promptly went out to the garage and pulled out 3 boxes of clean, empty green glass beer bottles. They are the kind with that hinged stopper top.
So a good deal got even better!! They had been washed before being stored, but with only a slight smile at my germophobe tendencies, he rewashed them all for me!
I would have preferred amber, but they are stored in a boxes in the basement, so no light hitting them anyway.
I feel a lot better knowing that my FO dollars won't be going to waste!!
