What a rip-off!  All over the page it says 3 count (Packs of 12).  Basically, they are packaged into a pack of 3 mustaches, and there are 4 of these packs stapled together, so "pack of 12"  Buyer beware!  Total rip-off!

Addendum:  Third party seller Bravofun was FANTASTIC.  Even though I didn't find out until about a month later re. the shortchanged mustaches, I contacted the seller, and they are sending a refund.  Still bummed that I didn't have them for Halloween, but am happy that I got a refund.  Would buy again without hesitation.
