Starbucks is selling color-changing tumblers and inventory sold out fast.
The reusable 24-ounce cups, selling for $16.95, change color when filled with a cold drink and are already a huge hit on social media sites just one week into sales, according to a USA Today report.
Social media reports indicate customers are literally calling around to various Starbucks stores trying to get the cups.
