Last week, Starbucks began selling color-changing cups in stores, Delish reported. The tumblers were an immediate hit - especially on social media. 

Starbucks fans applauded the chain for releasing a product that was not only Instagrammable, but that also encouraged customers to reuse cups. The coffee giant has been working to convince customers to stop using plastic straws, with plans to eliminate single-use straws by 2020.  

This week, however, excitement over the cups turned into a mad dash to try and find stores that still had the tumblers in stock. 

Some people are reselling the color-changing tumblers for significant mark-ups online. While the five-pack of cups cost about $16.95 in Starbucks locations, some people are reselling the cups on eBay for more than $50.

Thankfully, there is no need to pay the more than 300% markup to get your hands on the cups. On Wednesday, Starbucks tweeted that the cups will restock next week in the US and Canada.
