Oh, I know where to get them. I previously checked your link. But I need a half dozen or maybe a dozen 28-400's (allowing for spares since it's a PITA to source). That's $30 for 144 per your link. I have maybe 6 bottles

At least the shipping is free. But that's 5 bucks each for the half dozen I really need. The point of my post was to think ahead so you don't get into the corner I got into.
I put together a very complex $95 order for bottles here:
Glass Bottle Outlet
And they had everything I could possibly want, all the top options (dropper, polycone, standard cap) for every size EXCEPT no polycone caps for their 8 oz or 250ml size. The pricing was very good, and in the quantities I needed (unlike your link where caps are a one gross minimum unless you buy them with the bottles and I wanted spares). But they were missing that one size polycone cap. I figured I would get them somewhere else next time I order other stuff from some place that carries them. What a mistake

. But I really didn't want to start over, re-sourcing my list, because of those 6 caps I needed. But now I regret it because the standard foam lined caps do not always tighten, sometimes they "spin" when you try to get them tight. Not every size maybe or maybe not every bottle. But I have a couple of spinners and I use that size to store bulk mixed nic and 100mg nic. So I learned the hard way that polycone caps are very important to do this stuff as best possible.
Just as explanation, for most of my bottle sizes (1/2/4oz) I ordered droppers *and* caps, polycone if possible (no droppers on the 8oz size of course). I did that because sometimes I like droppers and sometimes I like plain caps and didn't want to think too hard so I ordered the bottles with droppers and then a full set of caps on the side. So I needed decent "each" prices for the caps.
