Good. I suppose I can can start looking around for half-used tubes instead of full ones. I used 3/4 of a tube on the last one I did. Maybe I did it WRONG, but it didn't leak.
Don't know about plenty at Napa. I bought the only tube left in a store within 250 miles. Memphis hub had one tube left. Ordered two from NPD, they had only one, so at least have two for the two cars I have to do coming up. ETA for back in stock is sometime in June.
