What is the cost of promo lotion packets with the attached session?

The correct answer highlights the promotional option that offers a session in conjunction with a packet upgrade. In tanning salons, promotional lotion packets often come with certain advantages, such as an upgrade to a more effective or luxurious product that may enhance tanning results. The price of $19.99 with a "packet upgrade" suggests that this option not only includes the packet but also provides an extra benefit, which appeals to customers looking for a better tanning experience.

Using a packet upgrade often enhances the effectiveness of the tanning session, making this choice particularly attractive for clients seeking improved outcomes. The other options may not include such enhancements or benefits, making them less appealing in comparison to the value presented by the packet upgrade.
