I used to drink a lot of soda, but a few years ago, I replaced Diet Coke with sparkling water, and I've never looked back.

Initially I bought a SodaStream as a way to save money, but I quickly realized that freshly carbonated, sharply bubbly water is superior in every way to store-bought sparkling water that's been sitting around in a bottle for who knows how long. Club soda is healthy and hydrating, and making your own seltzer means you're not creating plastic waste—and you can craft bespoke carbonated concoctions like a damn alchemist. Club soda/seltzer/sparkling water is the world's best beverage.

All this to say that this SodaStream Terra Sparkling Water Maker Bundle is on sale for Prime Day for $79.99, nearly half-off the list price of $149.99. (Okay, it takes a little time for the savings to start.) It even comes with Bubly Drops Flavors to get you started on the concoction-creation. Pro-tip: Bubly is fine because it's not sweetened, but don't try to be slick and get flavor syrups based on name brand sodas like Coke and Pepsi; they're really gross.

Looking for something else? Retailers like Walmart, Best Buy, and Home Depot have Prime Day competition sales that are especially useful if you don’t have Amazon Prime.

• Walmart’s Prime Day competition sale begins at midnight on July 8 and will include deals up to 50% off. It’s an especially good option if you have Walmart+. 

• Best Buy’s Prime Day competition sale, “Black Friday in July,” runs through Sunday, July 13 and has some of the best tech sales online. It’s an especially good option if you’re a My Best Buy “Plus” or “Total” member.

Home Depot extended its 4th of July sale through at least July 9, competing with some amazing deals of its own. It’s an especially good option if you’re looking for power tools, appliances, or outdoor equipment.
