It's the second week of October, which means Halloween is creeping (quite literally) around the corner. Not prepped? Don't fret! Walmart's Holiday Deals event, which runs through October 13, is chock-full of discounts on indoor and outdoor decor to ensure your best (read: most thrilling) Halloween yet. We're talking life-sized skeletons, iconic inflatables and even a fog machine marked down up to nearly 75% off and ready to ship in time for the frightful festivities.
