It’s no wonder Black Friday is the biggest shopping day of the year. Enticed by jaw-dropping doorbusters, unbelievable buy-one-get-one-free deals and irresistibly deep discounts, bargain shoppers across the nation flock to stores as soon as they polish off their Thanksgiving dinner. The average in-store discount for Black Friday is 37% and 24% for online products.

This means that customers should be strategic when it comes to what to buy – that big discount may not be on the thing you actually need. So which purchases should you skip this Thanksgiving weekend? Here are nine of the worst items to buy on Black Friday.

Winter Gear

While some clothing will be deeply discounted during Black Friday sales, retailers know many shoppers are in need of snow boots, cold-weather jackets, and other winter gear this time of year. Therefore, they’re much less likely to mark down this snowy weather apparel. If you can, hold off until January to buy these items, when many stores will kick off their winter clearance sales.

Cars

Historically, October is when you’ll find the deepest discounts at the car lot. This is because October is when dealerships are anxious to clear inventory to make room for the next year’s models. While you may find car deals on Black Friday, too, you would do well to wait for even better deals in December, as the auto industry is becoming more like the retail industry in offering end-of-year mega sales.

Furniture

Whether you’re looking to replace your shabby sofa or those rusty patio chairs, you probably won’t score phenomenal deals on indoor or outdoor furniture over Black Friday weekend. Typically, retailers don’t mark down indoor furniture until June when they’re trying to make room for the new product lines. And by late November, patio furniture sales are long over. If you didn't take advantage of them, try to make do until August when you’ll find deep discounts at next year's patio clearance sales.

Exercise Equipment

After you gorge yourself on turkey and pumpkin pie, you might be thinking about buying a treadmill or stationary bike. While these items can certainly help with your battle of the bulge, they’ll put a strain on your wallet during Black Friday. Put off your exercise-equipment purchase until January. That’s when fitness stores have the biggest sales on treadmills, elliptical machines, and other equipment, as they appeal to the New Year’s Resolution crowd and make room for new models.

Mattresses

Unless you’re absolutely desperate to replace your lumpy old mattress, hold off until May when you’ll find the biggest discounts on mattresses and box springs.

Airfare and Hotels

While you’ll probably see plenty of Black Friday promotions for hotel and airfare discounts, these sales are usually mediocre at best. Wait until December or January, when you’ll typically score the best travel deal. According to Hopper, a site dedicated to tracking airfare prices, domestic flights will be cheapest to purchase in December.

Gift Cards

Because gift cards are one of the most popular holiday presents, you may be tempted to load up on them during the Black Friday weekend. Try to resist the temptation. You’ll find the best deals on gift cards if you hold off until December or January.

Anything at the Apple Store

While you may bag an incredible deal on the latest and greatest Apple gadgets during Black Friday, you won’t find them at the Apple store. In previous years, Apple-authorized resellers have some fantastic deals if you're looking for an upgrade.

For Black Friday 2018, Target will be giving away a $250 Target gift card to anyone that buys and activates an iPhone XS or iPhone XS Max. If you’re on the hunt for Apple products, check out Black Friday deals at other retailers such as Target, Best Buy or Walmart.

High-End Jewelry

Now is not the time to buy your girlfriend that diamond engagement ring or pearl necklace. Jewelry stores may advertise can’t-miss Black Friday sales, but don’t fall for it. You won’t find the best deals on fine jewelry until the summer months.

The Bottom Line

While you can certainly find some astonishing deals and save a bundle on Black Friday, you should probably hold off on buying these nine items. This just isn’t the best long weekend of the whole year to purchase fine jewelry, furniture or cars – despite the car ads with the giant bows. On the other hand, you’ll find plenty of deep discounts and slashed prices on casual jewelry, books, movies, toys, kitchenware, appliances, and apparel.
