Thats really, really weird...
probably you added the entire US stock of them to your cart the same minute I tried to add them to mine. lol

Seriously though, no idea why it tells me they are out of stock and lets you buy enough to fill a hefty sack with them.

 

LMAO, Let me know if I can help

 

Sounds like the problem is solved. I'll just add for reference, there is a large ACE hardware near me that keeps a good stock of inverted flare stuff. I also order from In Line Tube.

 

In line tube didn't have them listed on their website, but they may still carry them. We don't have an ace near here, which stinks, since they usually do carry a lot of oddball stuff and their clerks usually know a lot more than the average autozone or home depot guy seems to.
