# Show Two Multiples of the Price Nearby

Something will "feel right" about the price.

### Overview

Compare these two pizza advertisements:

The left ad is economically superior because people have “unlimited” toppings. However, people were more likely to buy the second deal with “6” toppings (King & Janiszewski, 2011).

See the culprit?

It involves multiples of the price.

Your brain stores common arithmetic problems:

Over time, children are drilled on simple problems so that an association develops between operands (e.g., 2 x 6) and results (e.g., 12). These stored associations are called “number facts” (Baroody 1985).

Exposure to two numbers (e.g., 2 and 6) immediately activates the sum (e.g., 8) and product (e.g., 12).

In the pizza ads, the price of $24 seemed better when the ad was showing two multiples (e.g., 6 and 4). Customers misattributed this sensation: *Hmm, something feels right. I must want to buy this deal.*

When possible, show two multiples of your price:

**$15:**3-Day Sale for $5 Off**$120:**Get 4 Weekly 30-Minute Coaching Calls**$500:**Get 5 Bonus PDFs for Free ($100 Value)

**Caveat:** Show two — and only two — multiples. If your price is $12, many multiples (e.g., 2, 3, 4, *and* 6) will weaken the activation of $12.
