Online purveyor of food-quality containers.

Glass, plastic and aluminum jars, bottles, vials, tins, aerosol pumps, etc.

They sell by the piece as well as the case -- which can be 300+ items.

Examples:
4oz tin with clear lid $.68, $.59 when by the case of 312
4oz cobalt blue glass bottle with atomizer $1.03, $.97 when by the case of 144
5oz 'woozy' bottle (like a coke bottle shape) with lid $.68, $.55 when by the case of 120 (dripper lids $.06)

I have no affiliation with these folks, except that I ordered a couple of items, and they sent them free of charge as a 'merry christmas' hoping I'd order more. I feel an obligation to spread the word for hot-sauce makers, spice keepers, etc.

Note: Their atomizer sprayers are better at a straight-line spritz than a mist. I'd hoped to use the aluminum containers for oil, but it didn't work as well as I'd hoped for oil. I've got another that I'm going to try with balsamic vinegar, I may get better results with something less viscous.
