Prime Day 2018 is upon us. And that means if you’re an Amazon (AMZN) Prime member, someone who likes a good deal or simply have a pulse, you’re going to spend an inappropriate amount of time browsing the site for some incredible deals beginning July 16.

Naturally, you can expect plenty of tech deals this year. But before you click “Add to Cart,” or get fired for gross negligence for spending the entire 36-hour sale online rather than, you know, working, brush up on the best tips for buying everything from smartphones and laptops to TVs and smart home gadgets.

It’s also worth checking to see if your new TV offers high-dynamic range (HDR) compatibility. HDR increases the contrast ratio of the image on the screen making for a wider array of colors, as well as deeper blacks and brighter whites.
