Costco has introduced a small but seismic update to its famous $1.50 hot dog combo, marking the first significant change to the meal’s composition in more than 40 years.
Costco now allows customers to substitute a 16.9-ounce bottle of Kirkland Signature water for the traditional 20-ounce fountain soda. While the pairing has evolved, the price — which has remained a flat $1.50 since the 1980s — remains firmly intact.

Last time I was there, I’m pretty sure I put water in my fountain cup – from the little tab dispenser next to the lemonade. It is nice, fresh filtered water.
I like to do 75% Seltzer and 25% Lemonaide. It’s fizzy, refreshing, and not too sweet.
But yes, similarly, you can get Seltzer with the little side tab on one of the taps, usually Sprite I think.
