you might check at your local napa store. at pokey here in n.e. ark it is on sale for 6.49. i saw a sale sign in o'riley's store for 7.99 and pulled in and got 2 cans and took them to the checkout and the man said, "i can get that cheaper for you." he started messing with the machine and then looked in the phone book and i guess to get napa's phone number to put in the machine. evidently they were matching the napa store on it. i got another can. don't know if it's a local sale or nation wide.
