What size is the Starbucks reusable red cup?

The free reusable cup that Starbucks is gifting is a standard grande size (16 oz).

The limited-edition cup is made with 50% recycled content as part of the chain’s goals to reduce waste and features a gift-inspired design with the signature holiday red colour.

Starbucks chief marketing officer Brady Brewer said in a press release: “As we build on our strong start to the holiday season, we’re delighted to bring back our reusable red cup giveaway for the fourth straight year.

Starbucks gives a discount too

Starbucks is also giving 10% off when customers bring in their own reusable cups.

The promotion is part of the coffee chain’s target to reduce waste by 50 percent by 2030.

The chain said that the offer is available only in stores for the time being as they are currently testing safe options to allow customers to bring their own cups in drive-thrus.

Some people have already managed to get their freebies.
