Ever notice how lots of prices at the store end in $0.99? So did Eli from Philadelphia, and he asked us to find out why. Turns out, it’s a method retailers use to get us to buy something — and it’s not their only one. This week, we’ll learn about how our brains work when we’re shopping, why it’s hard to resist a sale and some of the ways physical stores encourage us to spend a little more money. Let us know what you thought about this season and what you want Jed and Bridget to do next! You can reach us at Marketplace.org/million.
