WASHINGTON (Reuters) -U.S. President Joe Biden on Sunday called on snack companies to stop shrinkflation, which is when businesses cut product sizes but keep prices the same, describing the practice as "a rip-off." "Some companies are trying to pull a fast one by shrinking the products little by little and hoping you won't notice," Biden said in a video posted on X, formerly known as Twitter, ahead of Super Bowl LVIII. Biden, who offered no solutions or policies to address the practice, did not name any specific companies but several brands were shown in the video, including Gatorade, Doritos, Breyers and Tostitos.
