Don't shop Amazon Prime Day without taking two key steps first, warn shopping experts

Amazon's Prime Day event is July 12 and 13 this year. The much-anticipated sale promises the deepest discounts on Amazon-branded devices and a variety of small kitchen appliances, among other offers.

However, not every item on sale on is worth buying or even that good of a deal, some shopping experts say.

Before you shop the sale, do these two things first to avoid making a mistake or having buyer's remorse while shopping on Amazon Prime Day.

Just because Amazon is boasting a low price doesn't mean it's a good deal, says Kristin McGrath, shopping expert at RetailMeNot.

"It's not uncommon for companies to mark up an item before putting it on sale, so knowing the product's price history is a great way to really know if the price you're paying is truly considered a good deal," she says.

To do this, you can use CamelCamelCamel, she suggests. The site tracks product prices on Amazon so you can see, for example, if the site hiked the price of smart watch up in June, only to bring it back to market rate in July and make it appear like a steeper discount.

To compete with Amazon, many other stores have started offering discounts on comparable products during Prime Day, says Mackenzie Shand, shopping expert at BlackFriday.com.

"Best Buy, Dell, Lenovo, Macy's, Nordstrom, and Target are all also hosting big savings events, also known as Black Friday in July sales, during this time," she says. "Shoppers should check out all the sales before purchasing to ensure they're scoring the best deals."

If you want to price compare, the app Yroo allows you to search for a product and then see, side-by-side, the price of the product at different retailers.
