FS New sealed REM40E spark plugs

I have 12 brand new Champion REM 40E spark plugs that I bought from Aircraft Spruce. They are still sealed never opened. Aircraft Spruce sells for $31.80 each. I'll sell for $25 each including shipping in ConUS.
I also have two engine driven fuel pump cores PN 103396-01. Make an offer.

Update

Sold four of the spark plugs. Eight still remain available for sale.

Four more of the spark plugs have been sold. Only four are still available. $25 each, you pay shipping
