Highlight the best option

You most likely have multiple prices. One of those prices is probably the best option. The one that offers the most value, the best features for the best price. Usually, this is the middle option, but it doesn’t hurt to bring a bit more attention to this.

Highlight the best deal using your design. Make it a bit bigger than the other options, give it a different color, add a sign that says “Best value” or “Most popular”. Use your design to steer users in a particular direction, and they are bound to follow.
