Starbucks has been promoting the use of reusable cUPS for years now. Many people believe that Starbucks still sells reusable cUPS. However, there is no clear answer because Starbucks does not release specific information about their reusable cup program. It is possible that Starbucks no longer sells reusable cUPS, but this information is not publicly available.
It is also possible that Starbucks still sells reusable cUPS, but the cUPS are not as popular as they once were. In either case, it is important to take into account the individual preferences of each customer in order to decide if reusable cUPS are right for them.
