Shopko started their 90% off Halloween sale today. They also have 90% off some fall decor which you could put out now for Thanksgiving.
Selection will vary from store to store. Earlier this week the N 27th Shopko in Lincoln, NE had lots of decorations, lights, baking supplies and costumes left. These really cool battery operated black lanterns caught my eye. They'd be perfect for my porch! The Shopko on 66th and O St in Lincoln only had a small rack of costumes.
I'm not sure what is left at the two S 27th stores. From previous experience, I'm guessing the Pine Lake one is more picked over than the Hwy 2 store.
Hurry! This stuff will go fast!
