Many items will be discounted, but some of the markdowns won't be that great. By Cameron Huddleston, Online Editor February 11, 2014 The Presidents' Day holiday on February 17 means a day off for some of us -- and the first big sales event of the year for retailers. Several retailers including Best Buy, Macy's and Walmart already have launched their Presidents' Day sales. And last year, some merchants continued their sales several days beyond the holiday, according to dealnews.com. So Presidents' Day sales can actually last for two weeks, rather than just the three-day holiday weekend. But do these sales really offer good money-saving opportunities for consumers? As always, it depends on what you're buying.SEE ALSO: Best Buys of Winter “Presidents' Day sales are a great way to save on big-ticket items,” says Offers.com Vice President Howard Schaffer. The sales are also a good opportunity to get deeply discounted cold-weather apparel for next winter for growing children by purchasing a size or two larger than what they currently wear, Schaffer says. However, he warns, watch out for new seasonal items such as spring clothing, grills and patio furniture that are promoted along with Presidents' Day sales items because they'll actually be at their highest prices of the year. Here are several items you'll see on sale around Presidents' Day, along with our advice on whether the discounts are worthwhile or just mediocre. Deep discounts on winter apparel. Most retailers already have put cold-weather clothing on clearance racks, with discounts as high as 70%. You can expect those sales to last through Presidents' Day, but you should be able to find coupons from most merchants that will let you get an additional 10% to 25% off clearance items over the holiday weekend, according to dealnews.com. In the past, some retailers have offered coupons for as much as 70% off clearance items, according to dealnews.com. Download a coupon app, such as the one from RetailMeNot, before you head to the mall to see which merchants are having sales and offering coupons. Don't expect widespread sales on shoes, though. According to dealnews.com, you'll see markdowns only on select items, but the discounts can reach as high as 70%. Advertisement Significant savings on select laptops. Dealnews.com saw some of the best prices of the year on budget laptops during Presidents' Day sales. This year, you can expect to see significant price drops on 15-inch and touchscreen laptops, according to dealnews.com. But don't expect bargains on powerful systems. For example, the deal experts at Deals2Buy.com alerted us to a Presidents' Day pre-sale at Dell, which has marked down a 15-inch Inspiron touchscreen laptop by $390 to $550. And apparently doorbuster deals aren't just for Black Friday anymore. Dell is offering some now and will have more February 17. Major markdowns on mattresses and bedding. Schaffer says you can expect to see these items discounted as much as 70%. For example, select mattresses are 30% to 50% off -- plus an extra 10% off sales prices -- during the Macy's Presidents' Day sale. And Macy's has marked down clearance bed and bath items online by an additional 25%. Sears has discounts of 60% or more on some mattresses. Decent discounts on large appliances. Look for discounts of at least 25% on select appliances at retailers such as Best Buy, Home Depot, Lowe's and Sears. However, you may find discounts as high as 50% off, Schaffer says. You may also be able to find coupons for a specific dollar amount off appliances, according to dealnews.com. Home goods at good prices. The best bargains will be on cookware and small appliances, according to dealnews.com. In addition to sales on these items, you'll probably be able to find coupons for an additional 10% to 20% off. Advertisement Lots of tool sales. You'll see lots of tool promotions, but most of the discounts won't be significant, according to dealnews.com. If you find tools marked down as much as 50%, you've found a good deal. Schaffer says you will find some discounts this deep. Otherwise, you might be better off waiting until July, when tools that didn't sell for Father's Day are deeply discounted. Mediocre electronics deals. Electronics retailers such as Best Buy, Newegg.com and even Walmart are promoting markdowns on cameras, tablets, televisions and more. But most of the deals won't be spectacular, according to dealnews.com. Several retailers already have marked down prices on 2013 television models, and we haven't seen additional discounts for Presidents' Day yet on six great TVs we recently recommended. The standard price cut (so far) on tablets is about $20, but Walmart has dropped the price on a Google Nexus 10-inch tablet by $100 to $399. And Newegg.com has marked down an 8-inch Samsung Galaxy tablet to $299 from $399.
