Want a new Hydro Flask? Here's how to get up to 40% off your next buy

Looking to upgrade your tumbler collection?

Hydro Flask is bringing back its trade-in promo from Oct. 23 to 26, offering up to 40% off select items when you trade in your old bottle.

According to the brand's Facebook announcement, customers can bring any clean and dry reusable bottle to participating branches to enjoy the discount.

Per promo mechanics, customers can trade in a reusable tumbler of any brand, size, or material, including both insulated and non-insulated bottles. Coffee tumblers, including those with flip straws or caps, will also be accepted.

Even tumblers with minor damage, such as broken handles, slight dents, or scratches, may be traded in, provided they meet the promo's other requirements.

Tumblers with major rust that makes them unusable, those with major dents, and bottles without lids or caps will not be accepted. Single-use plastics and disposable plastic bottles are also excluded from the promotion.

Customers must bring clean and dry tumblers for hygienic purposes. Each eligible reusable bottle traded in is equivalent to one Hydro Flask bottle.
