Costcojust upped their sparkling water game.

The superstore recently added three flavors to their Kirkland Signature line of fizzy beverages, and the new cans are strikingly similar to the cult-favorite seltzer LaCroix in both look and price.

The line from Costco’s private label already consisted of flavors like black raspberry, orange mango and kiwi strawberry, but now you can find flavored cans of lemon, lime and grapefruit seltzers on shelves—the same combination of flavors Costco already sells for LaCroix.

The Costco Connoisseurnotedthat the lime and lemon Kirkland flavors taste “exactly the same” as LaCroix, while some true fans may notice a slight difference in the grapefruit variety.

Multiple brands have been launching their response to the popular sparkling water, includingPepsiCo, which released a line of sparkling water, bubly, with zero-calories, no artificial flavors and no sweeteners earlier this year.
