Pools and hot tubs
The winter is the best time to purchase warm-weather luxuries, when prices are the lowest.
Plus, it's smart to give yourself several months to regrow the grass in your yard after it gets torn up during pool installation.
Since this isn't prime suit-shopping season, you're likely to get a good deal.
If you're looking for something a little less fancy, January's a great time to stock up on most types of clothing.
Take advantage of post-Christmas shopping deals.
The timing isn't ideal, but you can get great prices on Christmas decorations in January — according to DealNews, stores like Home Depot, Sears, and Crate and Barrel will cut up to 70% off the seasonal inventory.
Plus, it'll be one less thing to worry about when the busy holiday season rolls around.
This is the time new models typically hit stores.
That means it's a great time to buy one of last year's models or take advantage of a President's Day markdown on a newer one.
Most of the year's frilly frocks have made their way into store aisles by now, and retailers are in prime competition to get you to buy your gown from them.
It's not the most exciting purchase ... but you'll have to buy tax software eventually if you're doing your own taxes, so you might as well get it discounted.
According to DealNews, programs like H&R Block and Turbo Tax will slash prices by 30% to 50%. Keep in mind that the closer you get to April, the smaller the discounts will be, so you'll want to jump on these deals when you can.
Plus, it never hurts to get a head start on filing your taxes.

Plus, Di Vincenzo says this month is one of the best times for ocean visibility if you're planning to scuba dive to check out the area's marine life.
Flea market items
Di Vincenzo recommends spring as the best time of year to take advantage of flea markets and thrift stores.
Many are just opening after the winter and are chock full of spring-cleaning wares.
He also advises going at the end of the day — sellers are more likely to give you a steep markdown so they don't have to haul their goods back home.
April tends to be scattered with rainy days, so stores stock up on wet weather gear.
However, retailers have a small window of time to sell gear, as sunnier days are right around the corner. In order to move their inventory quickly, they'll offer enticing discounts.
Memorial Day mattress sales are not at all uncommon. They can be the best time to stock up on mattresses and box springs.
DealNews says not to settle for anything less than 50% off.
Stores will try to lure you into buying summer clothing, but the best savings during April will actually be on spring apparel — according to DealNews, you should wait to buy summer apparel in August and September.
Look for the biggest discounts on spring clothes during Memorial Day weekend.
Snag barbecue essentials — chips, crackers, ketchup, and relish, to name a few — by late May. You should be able to find markdowns on marinades and dressings as barbecue season heats up.

Typically, lingerie comes at a steep price, but you can score deals in June when Victoria's Secret unveils its semiannual sale, which typically lasts three to four weeks. The sale starts with most items 50% off, and after a few days, you'll find things for up to 75% off.
You won't be limited to Victoria's Secret, as many other lingerie stores follow suit during this time.
If you know which ones you'll need during your next college semester, don't wait to buy them.
Prices are lowest right after everyone sells them back.
Laptops and other school supplies
Although many students are finishing up classes or graduating in June, a bunch of retailers launch their back-to-school sales this month.
According to DealNews, the Apple Store typically offers an everyday educational discount, which can save you up to $200. And remember, stores like Best Buy and Amazon will generally match (or beat) Apple's prices, so you could walk away with a good deal.
If you're definitely going to buy a Mac, wait until after Apple's annual Worldwide Developers Conference, which kicks off June 13 — the company is expected to introduce a new line of MacBook Pros, meaning older models will see price drops.
Retailers often lower prices on bottled water when it's hottest.
Outdoor picnics and barbecues are common, and many people will buy a case of water before they head to the park.

August is when stores get their new models, so expect to see deals in July.
Obviously, fruit is at its best when it's in season — usually that means summertime.
Different varieties are best all year round, but July is the prime time for berries, melons, peaches, plums, and watermelons.

But if your box fan isn't going to get you through the heat of the summer, you're in luck — air conditioners will be cheapest in July, DealNews says.

While you're sprucing up your patio with new furniture, consider adding an outdoor grill. August tends to offer various charcoal- and gas-based grills at a hefty discount.
You have time to shop around — many of the sales on grills and grill accessories will spill over into September, DealNews reports.

If you didn't get your sugar fix in October, jumpstart the holiday season with discounted Halloween candy throughout November.
Your options may be limited, but the price tag is hard to beat.
Thanksgiving always involves time in the kitchen, and November is the time to stock up on pots and pans — according to DealNews, all kitchen appliances, including high-end devices, will be at their absolute lowest prices.
Bridal shops buy more dresses ahead of the holiday season engagement frenzy.
But if you start looking around Thanksgiving, you can beat the rush and find a more affordable gown.
The hype that Best Buy gets for its Black Friday discounts isn't unjustified.
Stores often give TVs and electronics huge price slashes to lure in Christmas shoppers.
You can score on things like laundry units, vacuums, dishwashers, and refrigerators in November, particularly during Black Friday week.
DealNews recommends keeping an eye out at stores like Sears, Best Buy, Home Depot, and Lowe's.
