9. You think impulse buys are at checkout, but it's aisle two they've set you up for
According to Dr. Brian Wasink, professor at Cornell’s Food & Brand Lab, grocery stores know that, in aisle two when your cart is still empty, you’re more likely to try new things. He calls this the vacuum effect. So, while there are impulse buys loaded near the register, the real adventurous buying tends to happen earlier.
10. They put expensive stuff right at eye-level Dr. Wasink recently did a study in the Atlanta and DC metro areas that suggested near 60% of purchases happened within 12 inches of eye level. That said, most of the cheapest options are on the bottom shelf. So, in the words of Lil’ Jon, “get low.”
