I recommend these Garmin smartwatches for almost every situation (and price range)

What happened

Prime Day begins June 23 and ends June 26. It's four days again, so you have four chances to find a good discount on something you want.

I spend lots of time writing about technology. I also think most of these sales events are marginally helpful for shoppers. It is more an opportunity for big retailers to reignite interest in their own products (and sell inventory) than it is an opportunity for shoppers to get good deals. Still, good deals exist during these events, so I'll tell you about them when I see them.

And if you just so happen to be in the market for one of these devices, I'll lead you in the right direction.

Why it matters

I've been covering these deals events for over three years now, so I can confidently say I know how these discount-paloozas go. Ahead of the event, I'd suggest you think about household essentials or products just out of your budget that you'd be interested in shopping during the many days of Prime Day.

While flashy, high-ticket items will go on sale, hit the front page of Amazon, and grab your attention, I'd recommend sticking to the stuff you know you need. That's how you can actually save money during a sales event.

Allow me to remind you that Prime Day is now a quarterly event, as Amazon has gotten even more voracious over making money through these days-long deals events. There's the Spring Sale in March, Prime Day in June, October Prime Day, and Black Friday, which now lasts a week, for some reason.

This year, Amazon Prime Day runs from Tuesday, June 23, to Friday, June 26.

What to watch

I use established price comparison tools and trackers to determine whether the deal is actually on sale and how frequently it drops. As someone with great familiarity with these products, I also remember the prices of these products and when they've gone historically lower or higher. This helps me determine if it's actually worth buying. If it's not, I'll tell you so.
