What $1 Flip-Flops Early???

I was reading the paper today and noticed an ad from JC Penney.  On the cover of the ad was a rainbow assortment of flip-flops.  What struck me about this ad was the $1 Family Flip-Flops in every color while supplies last.  Why is that so odd?  Normally I get my flip-flops at Old Navy which normally only offers select colors and is normally not until May or June.  It looks like Old Navy has some competition this year. 

I am not one to match my outfit with my flip-flops, but if I was this would be one sale I would be heading to.
