"What started as a single hot dog cart turned into Costco's iconic court, delivering everything from hot dogs plus a 20-ounce soda for $1.50 to a slice of pizza for $1.99. We've ranked every Costco food court item, and many of them are great for refilling your tummy on the cheap. But one secret that some people might not be aware of is that there's another thing you can refill here for free: your soda."
"Lots of Costco members and employees alike have chimed in on this on Reddit. The consensus is that so long as you don't go overboard and stay for hours to burn through a dozen cups of soda, or drain the fountain into 55-gallon drums, you should be good. Costco has huge markups on soda, so much so that you'll need to drink a truly egregious amount (like 10 refills) for them to begin to make a loss on the $0.69."
Costco food court offers a 20-ounce soda cup labeled "with refill," though the singular wording can be misleading. Members and employees report that multiple refills are typically allowed if customers do not excessively consume soda or attempt to drain the fountain. Costco's soda pricing includes large markups, meaning a customer would need an unusually high number of refills (around ten) to cause a loss on a $0.69 item. Customers may use a tumbler or travel mug for refills after notifying an employee, and using the paper cup to transfer soda into a personal container is cleaner. A coke float pairs well with refills.
