It looks like some Target stores have hit 90% off clearance on Christmas items.
Now this will vary considerably from store to store- some stores will not hit 90% at all.
Other store will likely drop to 90% off tomorrow.
If you are still on the lookout for odds and ends, you might want to give your store a call and ask. I tend to buy a lot of the fancy wrapping paper at this time of year. I can use it next year or you can unroll it in the summer and let the kiddos paint and color.
You can see the Shop for Free list for Target here. There are a lot of great deals!
