Shoppers of Dell Australia’s website who were buying a computer would see an offer for a Dell display with a lower price next to a higher price with a strikethrough line. That suggested to shoppers that the price they’d pay for the monitor if they added it to their cart now would be lower than the monitor’s usual cost. But it turns out the strikethrough prices weren’t the typical costs. Sometimes, the lower price was actually higher than what Dell Australia typically charged.

Don’t believe in ads, folks. If prices are important for you, do you own research.
