If you regularly shop online, chances are you're familiar with cashback rewards and other crucial terms every online shopper should know.

Using cashback websites is one of the easiest ways to get more out of your buying experiences. They help you "earn back" the money you spend so you can make your shopping budget stretch further. Instead of visiting a retailer's website directly, you buy your products through a cashback site. From there, you can shop like you usually do but you have the chance to get some of your cash back in your account.

In this article, we've highlighted the best cashback sites that enable you to save money while shopping for anything, ranging from tech gadgets to clothing and even food.

1. ShopAtHome (Web, iOS, Android)

With over 3,000 online vendors (including retailers like Wal-Mart, Ralph Lauren and Bath & Body Works), ShopAtHome is a cashback site that can save you money on just about anything. Signing up for an account on the site is free and, once logged in, you can start hunting for online and in-store cashback deals.

Note: You must be logged into your ShopAtHome account before clicking into any of the retailers' sites or your cashback rewards may not apply.

You can also earn cashback by accumulating points in the ShopGold Rewards section. This section of the site gives you points for taking surveys, playing games and inviting your friends to become members. 2,000 ShopGold points earns you $20 in gift cards, 4,000 earns you $40, etc. Your Gold Rewards points can be redeemed for gift cards only---no checks or PayPal deposits.

In terms of redeeming the cashback you earn from shopping (which is different than the ShopGold Rewards), you need to acquire a minimum of $20 in cashback in order to receive a rebate check from the site. Most cashback deals are based on purchase percentages and range from 1.5 to 20 percent cashback.

2. Coupon Cactus (Web)

Coupon Cactus provides cashback from over 4,000 retailers, including Target, Old Navy, Sears, and Walmart. Signing up for an account is free and the site will give you $3.00 for doing so.

This site offers a nice variety of coupons; some will get you a flat dollar amount off from your purchase through select retailers, while others are based on a percentage of your total purchase amount. Every retailer's coupons have their own stipulations and vary in terms of the amount of cashback you'll get.

It's nice that the minimum redemption amount for Coupon Cactus is less than many other cashback sites---only $10.00 You can get your cashback via a check or PayPal and cashback amounts are paid to site users once every three months. Also, if you don't quite earn $10 cashback, Coupon Cactus will let you keep what you did earn and roll it over into the next payout period.

3. Ebates (Web, iOS, Android)

Ebates is free to use and offers cashback deals for a variety of retailers including Nordstrom, Panasonic, Groupon, and Amazon. When you make your first purchase via Ebates you earn a bonus gift card for $10 (if you want to apply it to Macy's, Wal-Mart, Target or Kohl's) or $5 (if you go want to apply it to Ebates).

Ebates lets you earn cashback from over 1,800 retailers and, to date, have paid over $250 million to its users. Much like Coupon Cactus, Ebates sends you your cashback rewards once every three months and gives you the option of receiving your money via check or PayPal.

Like the other sites discussed here, Ebates' retailers offer varying degrees of deals, most of which are a percentage of how much you spend on the retailers' sites. Some rates hover around 1.5 to 2 percent, while others allow "up to" 12 percent or more. One especially nice feature about Ebates is that it features "Double Cashback" deals, where retailers are offering twice as much the cashback as they normally would.

4. BeFrugal (Web)

BeFrugal is a cashback site that works similarly to Ebates. When you shop through BeFrugal, you earn cashback at hundreds of different websites. If you install their browser extension, it'll alert you about cashback offers while you browse.

Other ways to increase your savings here are searching for promotional codes, coupons, and deals on the site. Check the Deals section of the site for fresh limited-time offers and daily deals.

BeFrugal allows you to get paid by check, direct deposit, PayPal, and gift cards. Creating an account on the site is free and when you sign up, you also receive a $10 bonus.

5. Extrabux (Web, Chrome/Firefox)

This site allows you to compare the prices, cashback rewards and coupon codes of items from over 2,500 merchants. Registration is free, super easy and takes all of 10 seconds (unless you have a really slow Internet connection). Signing up also earns you $5.00 automatically and gives you access to all of the site's coupons and cashback deals.

Coupons on the site allow you to redeem a code for a set dollar amount or a percentage off on select products from retailers like Macy's, Amazon and New Balance.

Of course, you also get cashback on your purchases---some of which even apply to coupon discounts! This is quite different from many other cashback sites, most of which allow either cashback or the use of a coupon, but rarely both. Cashback deals on Extrabux range from about 1 percent to 15 percent back on select items.

Another big appeal of using this site is its free browser extension. Other sites may require you to log into your account and search for deals within the cashback site before clicking through to the product you want to buy. Extrabux lets you log into your account via the browser extension and then tracks your cashback as you search the web, even if you go directly to retailers' sites.

A $10 minimum is required to receive your cashback via Alipay, PayPal or check and, like many of the other sites on this list, Extrabux rewards you when you refer friends to the site.

6. Swagbucks (Web, iOS, Android)

Swagbucks has a unique cashback system. Instead of points, users accumulate a virtual currency called Swag Bucks. You get more of these Bucks by doing things like shopping, playing games, answering surveys and searching the Internet.

This cashback site currently has over 13 million members and has paid more than $90 million in user rewards. Sign up is simple and free and you earn four free Swag Bucks when you do so, and two more when you set your security question. The site also offers to show you the ins and outs of earning your rewards with a quick and helpful tutorial.

One feature of Swagbucks that sets it apart from other cashback sites is its "Accomplish Channel," located to the left side of your screen in the Web version. Using the Accomplish Channel, you can set daily cashback goals and track your progress towards said goals. You can also make To-Do lists to track easy ways to earn more cashback and connect your social channels.

Swagbucks also lets you enter Swagstakes, which are like sweepstakes, but with more swag. Swagstakes are essentially like gambling with the cashback you've earned. Swagstake prizes range from Swag Bucks giveaways to monetary gift cards.

7. TopCashback (Web, iOS, Android)

TopCashback's tagline is "USA's most generous cashback site"---and boy, does it live up to it. Aside from having no minimum payout threshold (meaning you can receive a check whether your balance is $.01 or $100), the site also transfers 100% of its affiliate commissions from partners to its users.

One interesting feature of TopCashback is that you can also earn cashback when shopping offline. Simply go to the Printable Vouchers section of their website after you sign up and print out the coupons you want to use during your in-store shopping. The only catch with this feature is that printable vouchers seem to be much less popular than online vouchers and TopCashback doesn't always have them available.

In terms of shopping online, TopCashback offers earnings from purchases through Wal-Mart, Amazon, American Eagle Outfitters and Apple. Most cashback rates hover around 3 percent to 7 percent cashback, but you can also find deals for 10, 12 and 15 percent cashback. Additionally, some retailers offer fixed dollar amounts back, which range from $50 to $100.

TopCashback also offers coupons and cashback for retailers in the UK and India.
