Ah, Thanksgiving. It's the time of year for counting our blessings, stuffing ourselves silly with turkey, spending time with family – and scoring major discounts on clothes, toys and electronics. If you're looking to land some phenomenal post–Turkey Day bargains, you basically have two choices: You can skip the family Thanksgiving feast, camp out in the parking lot of your favorite store and fight your way through a mob of rabid bargain hunters at the break of dawn on Black Friday. Or you can roll out of bed on Monday morning, pour yourself a cup of coffee and browse online for rock-bottom prices – all while you're still in your PJs.

If you opt for door No.2, you're in luck. On the Monday following Thanksgiving, coined Cyber Monday, countless shopping websites slash their prices and offer their biggest discounts of the year. Better yet, some online retailers serve up the same deep discounts as brick-and-mortar stores on both Black Friday and Cyber Monday.

In 2014, the Black Friday/Cyber Monday online deals were so appealing, many shopping websites were overwhelmed with visitors. While some sites slowed to a snail's pace, others (including HP.com and BestBuy.com) crashed altogether. Even so, Adobe reported ecommerce sales hit record highs on both Thanksgiving Day and Black Friday 2014, topping out at $1.33 billion and $2.4 billion respectively.

So which online retailers will offer up the best Cyber Monday deals on November 30, 2015? Here are seven websites where you'll likely find the deepest discounts:

As the world's No.1 online retailer, Amazon sold a whopping $89 billion worth of products in 2014. (For more on this, read How Amazon Competes with Google.) The wildly popular shopping website has even surpassed Wal-Mart Stores, Inc. in market value. Each year, Amazon offers major deals on both Black Friday and Cyber Monday, and millions of shoppers flock to the site during these supersales. On Black Friday last year, the site attracted around 173 million visits.

This year, Amazon promises an even more exciting Black Friday than last year, including major sales and reduced prices on electronics, video games, clothing and more. Plus, the online retailer will continue its deep discounts on Cyber Monday. If that's not enough, Amazon often mixes multiple Deal of the Day promotions with time-limited lightning sales, resulting in even bigger savings. And for Prime items, two-day shipping is free for Amazon Prime members.

In 2014, Best Buy dished out some shocking Cyber Monday doorbusters and deals along with free shipping on all orders over $35. From $30 to $100 discounts on first generation iPad Air tablets to $150 to $900 off select Samsung HDTV models, the electronics retailer offered some mega-deep discounts last year.

This Cyber Monday, BestBuy.com vows once again to slash prices on popular electronics, gadgets and technology products, including laptops, HDTVs, Blu-ray players, digital cameras, cell phones, video games, health and fitness gear, music, movies and more.

Despite Amazon.com, Inc.'s higher market value, this Goliath big-box store still trounces Amazon in overall sales, with about five times the annual revenue.

Yet as Walmart races to keep up with Amazon, the big-box retailer is throwing big bucks at its ecommerce business, even developing its own online subscription service to compete with Amazon Prime. Consequently, Walmart.com will likely offer deeper discounts than ever before this Cyber Monday.

On November 30, 2015, Cyber Monday will kick off an entire Cyber Week at Walmart.com. During this weeklong marathon of savings, Walmart.com will offer amazing values on electronics and other fantastic gifts, including some of the season's most-wanted items, according to the website.

Like Walmart, Target offers seven days of online savings during its Cyber Week, when the retailer slashes prices on electronics, toys, household items and electronics. During Target's Cyber Week 2014, Our Generation dolls were 50% off, Star Wars and My Little Pony toys were buy one, get one half-off and a Samsung 40-inch Smart LED HDTV ($379.99) came with a free $30 Target gift card. The retailer also offered free shipping on every purchase through December 20. Target.com visitors can expect similar Cyber Week deals this year.

During last year's Cyber Monday event, JCPenney.com offered 50% off five star mattresses, up to $40 off Faberware cookware and an extra 20% off any purchase of up to $100 on apparel, shoes, accessories and home goods.

In one Cyber Monday 2015 teaser on its website, JCPenney hyped this year's amazing savings and deals on countless different items, including apparel, accessories, furniture, home decor, small kitchen appliances, cookware and more. Customers can sign up for Cyber Monday sales email alerts at JCPenney.com.

Serving up significant sales on apparel and household items, Macy's is another star on the Cyber Monday scene. In 2014, Macys.com offered some deep discounts, including 30% off KitchenAid and Cuisinart mixers and food processors, 60 to 70% off select comforters and 60% off men's jackets, women's dresses and coats and juniors' coats. Customers can expect more of the same in 2015.

Not only did Macy's offer up some remarkable Cyber Monday deals in 2014; the department store fan favorite also generated the most interest on Facebook during last year's post-Thanksgiving shopping season. According to BI Intelligence, Macy's Facebook posts were liked, commented on and shared more than 370,000 times on Black Friday and Cyber Monday– beating out both Amazon and Walmart.

The world's leading toy and baby products retailer, Toys R Us, really knows how to throw a cyber sale. In 2014, the toy store kicked off Cyber Week early starting the day before Thanksgiving and continuing an 11-day sales marathon through Cyber Week. During the prolonged sale, deal-seeking shoppers scored deep discounts on the most sought-after toys, including kid favorites like Barbie, Frozen, Fisher-Price toys, LEGOs, Teenage Mutant Ninja Turtles and more. Last year, Toys R Us offered free shipping on purchases of $49 or more – but this September, the retailer dropped its minimum free shipping price to $19.

If the thought of unruly swarms of shoppers and insanely long lines sends chills down your spine, you should probably skip the Black Friday brick-and-mortar sales at big stores. Why not bargain shop from the safety of your computer or mobile device instead? Although these seven online retailers are renowned for their Cyber Week sales, this is just a handful of the hundreds of online retailers that will be offering mega-discounts, slashed prices and free shipping post–Turkey Day.
