Long lines have formed outside stores overnight and fights have broken out as people rush to purchase limited edition Stanley insulated tumblers sold at Target and Starbucks, which then resell for much higher prices online. The most sought-after styles are the pink Starbucks collaboration cups and the Target "Galentine" collection cups released in December, which now sell for up to $400 on eBay. A viral video of a woman's car fire being put out by her Stanley cup that stayed cold increased interest in the brand.
