Summer is past its halfway point, which means the first day of school is just around the corner. This reality might produce some groans among the kiddos in your lives, but parents can revel in the fact that BTS sales abound. This week, the hottest discount in town may be on Owala’s site.

You heard that right: The fan-favorite water bottle brand is hosting a rare sale. Everything (yes, everything) on the site is marked down 20%. The sale only lasts until Aug. 8, so there are only a few days to grab what you need for your kids, yourself—and maybe a few early holiday gifts, if you have the brain space to think that far ahead.

Here are a few of our favorites to consider during your Owala shopping spree:

The reason Owala is what it is. This sleek water bottle is well-loved because it’s leakproof and comes in a rainbow of colors. Contributor Ali Francis adores this water bottle because “the mouthpiece is designed for two types of people: those who will only sip and those who live to chug.” Get it now for the markdown price of $24.

Same bottle, sized down for younger hydration needs. This version for the littles is praised for all the same reasons as the standard one. Right now, the 16-ouncer is only $20, so we think you should grab a backup or two.

Already have an Owala water bottle? Take advantage of the markdowns and stock up on extra lids, straws, and gaskets. Or, grab a silicone bottle boot to keep your Freesip from tipping over or sliding off the counter, or some cleaning tablets to keep your bottle in tip-top shape.
