in 2020, with the COVID-19 pandemic causing 7-11 Day's cancellation that year. In Australia, free Slurpees are given on November 7 (7/11, day/month) to coincide with 7-Eleven day. In 2010, 7-Eleven teamed up with Sony to create limited edition promotion cups for the PlayStation 3 games LittleBigPlanet 2 and Killzone 3. In 2011, a Slurpee themed t-shirt was added as DLC to LittleBigPlanet 2. Since July 7, 2011, 7-Eleven has partnered with Cinemark Theatres marking the first time Slurpees are sold outside its parent franchise. 32 theatres were chosen in Houston, Texas; Dallas, Texas; and Portland, Oregon. This marks the first reappearance of the Slurpee brand in the Houston metro area since 1990 (all 7-Elevens in the Houston area were sold to National Convenience Stores that owned Stop-n-Go; all Houston-area 7-Elevens were rebranded as Stop-n-Gos until Diamond Shamrock acquired the franchise in the late 1990s, now part of the Valero conglomerate of crude oil refineries and retail convenience stores most commonly operated under the Valero brand with generic names, though some Texas-area stores retained Corner Store branding held over from the Valero purchase of Ultramar Diamond Shamrock in 2001). 2012 has the Slurpee being sold at the Six Flags amusement parks chain in a marketing agreement to promote the product in 10 states. In Australia on 21 September 2011, customers could bring in their own cups (or container, regardless of size) and fill it full of Slurpee for only $2.60 (a portion of the price of a Super Slurpee) as long as it would fit through a cutout hole limiting the size. This did not stop people from receiving up to and above 5 liters of Slurpee for less than the price of a Super Slurpee. This event was known as Bring Your Own Cup Day. Since 11 April 2015, Bring Your Own Cup Day in U.S locations originally occurred once annually since 2022; semi-annually from 2016 to 2017. Slurpee fans could come in and enjoy any size cup, that fit through the cutout hole, for only $1.49 the first 2 years. This promotion occurred again on 19–20 August 2016 in honor of the Slurpee's 50th anniversary. It returned on 19–20 May 2017, but the price was $1.50 plus tax, and returned once more on 18–19 August. Late August 2022 saw its return, but is priced at $1.99 plus tax. There was no Bring Your Own Cup Day promotion in
