What does to pie in a poke mean?

"To pie in a poke" is an idiomatic expression that means to make a purchase or commitment without inspecting the item beforehand, often leading to regret or disappointment. The phrase originates from the practice of selling a pig in a sack (or poke) without allowing the buyer to see it first. Essentially, it warns against making hasty decisions without proper evaluation or knowledge of what one is getting.
