Red Hot Summer Clearance. It feels like it's a bit early, but there are thousands of deals here, so I'll keep my guessing to myself.
Choose from apparel, electronics, patio and garden, toys, sports/recreation, home items, jewelry, tools, and more. I recommend it for back-to-school shopping or buying that random summer item (pools, squirt guns, outdoor furniture) since those are the most discounted.
