I’ve been disappointed that TARGET has not had a seasonal LEGO polybag set, especially for Halloween, lately. However, if you are into Halloween, LEGO does have a Halloween holiday set that looks appealing:

(… unless of course, you already HAVE a bunch of jack-o-lantern pieces that you’ve never used.)
I too am unhappy that there is no halloween polybag at Target. I have been up there a few times looking.
