Use These Tips to Shop Smarter at Amazon for Memorial Day Deals

Giant sales events like Memorial Day can be great opportunities to pick up more expensive products you had put off buying for later such as TVs, laptops or furniture. When shopping Amazon, there are plenty of ways to save on top of what the deals offer (and some common mistakes to avoid).

Here are eight tips to help you get the best prices -- or even money back -- at Amazon.

Many Amazon Memorial Day deals are for Prime members only, but we won't hold it against you if you're hesitant to kick in a yearly $139 fee just to save money elsewhere. You can, however, try Prime for 30 days and take advantage of its features. After the period is up, you're automatically charged for the Prime Monthly plan at $15 per month (which calculates out to $180 per year) unless you cancel.

And if you do choose to stay on Prime, be sure to use these Amazon Prime perks.

In the physical retail world, clipping printed coupons can get you discounts at local stores with only a small amount of effort. That idea has crossed into Amazon shopping with a small coupon checkbox. Just like the physical coupons, you have to take action on an Amazon item when a coupon is available. Click that box!

Want to find more products with coupons? Look for the Coupon Deals section to browse current click-it discounts.

Is anyone clamoring for more notifications? When they're actually targeted to your interests and relate to a specific event such as Memorial Day sales, they can be useful. In the Amazon app on your phone or tablet, view your account (tap the person icon) and locate Deal alerts or Deals and recommendations in the Message center or Notifications settings (the specific location varies by operating system).

When you're looking at an item on Amazon, look below the large listed price to see if there are other variations. Prices may vary for other colors -- a purple one might be on sale, but the standard black could be even cheaper. Or perhaps Amazon is looking to offload unpopular colors or patterns.

What if you don't have Amazon Prime? Sure, Amazon prefers that you join its membership club (which has a host of perks), but it's not necessary to take advantage of huge savings. Amazon Warehouse Deals include discounts for preowned, used and open-box products in nearly every category.

Online ordering is convenient and can be done at any time of the day, but it's still a hands-off experience. Without seeing something in person, there's always the risk that an item won't fit, is larger than the photos suggested or just isn't right for some other reason. If you think you may need to return something and you have an Amazon Echo smart device, order it using Alexa. Physical merchandise (except Amazon Pharmacy items) ordered via Alexa Voice Shopping can be returned for free regardless of reason.

Is a big Memorial Day sale too stressful to wade through? For items you use regularly, sign up for Subscribe and Save, which provides a recurring discount of up to 15% and automatic shipping on a schedule you set. Say goodbye to hazy precaffeine mornings when you realize you're out of coffee filters -- new ones will arrive before the old ones are used up.

The tactical application of a credit card can save you money, earn cash back on purchases and knock off a big chunk of your Memorial Day purchases. If you're a Prime member and qualify for Amazon's Prime Visa, you can start off with a $100 gift card upon approval. You'll also get 5% cash back on items you order via Amazon's website, Whole Foods and Amazon Fresh and 2% back at many other vendors.
