Halloween // Code Orange for Michaels?

Anyone know about when would be a good time to hit up Michael for their decor? I wanna be on top of it this year, after I found out a little too late about their bomb-ass pastel goth collection (those that know, you know) and was only able to get a few things

In that same vein I don't wanna be going there constantly to just walk in, see there's nothing and immediately leave, it wastes time, and I feel it comes off as weird
