Is your family gearing up for Halloween? Have you decorated? Planned your costumes? Kmart can help with all of that and more. They've got some fabulous deals going on right now too! Every Friday and Saturday leading up to Halloween, costumes are 50% off! We planned early this year so we already had our costumes before I went shopping at Kmart but they have a really large selection of costumes. I was seriously impressed. From baby costumes to adult costumes with some pretty creative options…
