The ebay heatsink post is $11 + $5 shipping ($16).

Your cooler + thermal paste is $60.

Altogether that is $76.

If I were to buy this new from mwave, it would be $70 + $9.29 shipping so say $80 http://www.mwave.com/mwave/SKUSearch.asp?px=FO&scriteria=AA82255

I don't really need this item you're selling, but I'll offer you (for the whole thing) $35 shipped.
