Live Long and Prosper! Today, you can order a Captain Kirk & Klingon Kor Mr. Potato Head 2 pack and/or Spock and Uhura Mr. Potato Head 2 pack for only $12.99! Shipping is always a flat rate of $5, no matter how much you spend.
I did some checking and these same sets go for much more than this on Amazon. The lowest price is around $25 shipped for each set. The reviews on them are actually pretty good, so you might want to look those over before you buy.
I honestly did not even know that they made such a toy! What the perfect add on item for any Star Trek fan collection.
