Where can I get the Motorcraft spark plugs cheaper than $6.39 each?

[SHOBrad]

Ford Parts Network has them (the AWSF-32F M plug of course) at $6.39 each! Any place better to get them? I don't have a buddie at my local dealer so no luck there!

Thanks,
Brad

When I got them from FPN, I paid like $4. Dunno

Got them for $3.71 from the local Ford. Had a firend with a business buy them for me at "shop cost"
