I discovered this website a couple years ago called Overstock.com. They have some really good deals on a lot of stuff. The main categories are furniture, home and garden, bed and bath clothing, jewelry, electronics, and sporting goods to name a few. They also have some tabs on top for auctions, cars, real estate, and community.
Some of the stuff I have bought in the past I saved as much as 60% off the retail price. Overstock is always offering free shipping or very low shipping rates. Today they are offering $1.00 to ship your entire order** note there are some exclusions.
Make sure you check out the Sales tab on the right of the page as they have different categories like Red line deals, clearance rack, new arrivals, top sellers, and almost sold out. I try and check this once a week and have found some great deals.
Let me know if you find some good deals!
