There’s a Wikipedia article about this hotdog. Some of my favorite quotes:

• In 2009, the Seattle Times asked Costco co-founder (and then-CEO) Jim Sinegal, "If [the price of the hot dog] ever goes up, what will it mean?" Sinegal replied, "That I'm dead."

• Craig Jelinek, the current CEO of Costco, revealed in 2018 that he approached Sinegal about raising the price of the hot dog combo, saying, "Jim, we can't sell this hot dog for a buck fifty. We are losing our rear ends." According to Jelinek, Sinegal replied, "If you raise the effing hot dog, I will kill you. Figure it out."

• In 2022, Costco CFO Richard Galanti stated that Costco intends to keep the combo deal's price constant "forever."
