Target has these great Batman and Superman slippers for men (heck, or women) for only $11.89 with 30% off promo code JOY30 (valid on all regularly-priced merchandise).

These men’s come in Medium, Large and ExtraLarge. After the JOY30 promo code, you’ll pay $11.89 with free shipping. Even less with REDcard.  I like the indoor/outdoor outsoles on both.
