I have several eye dropper glass bottles that are crap since I rarely use a dripper. I bought a load of 30 and 50ml plastic bottles out of eBay and use those. I mix and steep my mixes 100ml at a time in wire top glass jars then transfer into the 30's, the 50's are for my wife so I don't keep on refilling her bottles as often. I may live in a small town but we have a apothecary and they supplied me with all the 50 and 100ml amber and clear bottles I want cheaper than I can order them online. I did find some cobalt bottles in a health food store but they wanted $3.50 for a 50ml bottle and it comes with a eyedropper...YUK.
