I was going to get some copper autolite 764 where is the cheapest place to find these? Or is there a better plug that i should use??

I bought mine at the WalMart on Florin Rd near 99....they were 1.94 for a pair...so 8 bucks total!

I just put the copper Autolite 764 in my car today they cost me $1.68 each. I pulled out the stock ones and they were in bad shape, and I only have 33,000 miles on my car. My Stang runs so much better now.
