When you think of Labor Day sales, you probably think of mattresses, right? While it's true that you can get some great deals on stuff for sleeping, you can also save big on stuff for your kitchen and dining room. Here are some of the best sales happening this weekend.

Get up to 40 percent off Appliance Special Buys, which include things like this Samsung Side-by-Side Refrigerator (now $998 instead of $1,329) and a GE Slide-in-Range for $997 (instead of $1,799).

Select home items at Target are 30 percent off and you can save another 10 percent if you use the promo code HOME at checkout. For example, this Hudson Filament Swag Light, which would look amazing over an island, is on sale for less than $41 and you'll get another 10 percent off.

Touting it their biggest Labor Day sale ever, Overstock is offering up to 70 percent off and free shipping when you spend $45 or more. Save on area rugs, patio furniture, and kitchen finds (including this Kitchen Island for a little more than $300).

Now through September 18, World Market is marking down all dining furniture by up to 50 percent and open-stock dinnerware pieces by up to 30 percent. Take advantage to get this Gold And Marble Leilani Tulip Dining Table (for $323), or any other dining table for that matter.

Take up to 70 percent off outdoor furniture, browse dining furniture that starts at just $49, and shop kitchen gear — also at up to 70 percent off. We're eyeing this Cuisinart Frozen Yogurt, Ice Cream & Sorbet Maker for less than $50.

Until September 5, Lulu & Georgia is having a tiered sale: Take 10 percent off $300 with the code GOOD, 15 percent off $550 with the code BETTER, 20 percent off $800 with the code BEST, and 25 percent off $1,500 or more with the code BANANAS. Save on small accessories, or splurge on that dining room furniture you've been eying — like this Zelia Bar Cart.

Planning a kitchen renovation? Save up to 35 percent on custom cabinets ordered in the store, get wood-look tiles for 99 cents each, and save up to 40 percent on select appliances. Even some faucets, like this Kohler one, are on sale.

The more you buy at West Elm this weekend, the more you'll save. Spend at least $100 and you get 15 percent off. More than $500 (ahem, this Mid-Century Buffet) will get you 20 percent off, $1,000 gets 25 percent, and a whopping $3,000 will save you 30 percent.
